Supercritical fluid (SCF) solvents are unique in that their densities can be varied continuously from gas-like to liquid-like values simply by varying the thermodynamic conditions. Because many of a fluid’s solvating properties are strongly dependent on the fluid density, such large changes in density can have dramatic effects on solute reactivity [1,2]. For example, at low pressures supercritical water supports homolytic, free radical reactions, whereas at higher pressures, heterolytic, ionic reactions dominate [3,4]. Thus, thermodynamic control of SCF solvent densities promises to enable us to control reaction outcome and selectively produce desired products.

    For anything other than hard-spheres, the size of a particle is not well defined — one could choose anything from the distance of closest approach between two particles at zero energy (σLJ), to the distance of closest approach observed at liquid densities (< σLJ), to the separation at the van der Waals minimum (> σLJ), to the mean volume available to each particle (1/p). In the present work, the radius determining the excluded area of the central particle was taken to be 0.73 σLJ in the case of the smaller local radius pt = 1.78 σLJ and 0.9 σLJ for the larger local radius pi = 3.09 σLJ. [35] We chose the excluded area used in the former case such that at the liquid density of 0.711 σ-2lj the mean local density (pi), see below, is equal to the bulk density. This removes pure structural effects, i. e. the solvent shell structure, from our analysis of the local densities. The exact value chosen is less critical at the larger radius, and here we simply used the value at which the radial distribution function first becomes non-zero in the liquid. A detailed discussion of how the choice local radius and excluded area are interrelated and affect the interpretaion of the local densities is given in Ref. [35].Google Scholar

    The critical parameters of Tc = 0.477 and pc = 0.38 σ-2lj for the truncated (at 2.5 σLJ), ueshifted, 2-dimensional Lennard-Jones fluid are taken from Ref. [104]. These are better estimates of the critical parameters than were used in our earlier studies of the same system (Refs. [9], [10] and [13]). Thus, the reduced values Tr = T/Tc and pr = p/pc differ slightly from previously quoted values. For example, the state T = 0.55 and p = 0.30 σ-2LJ was previously given as Tr = 1.17 and pr = 0.86, but becomes Tr = 1.15 and pr = 0.79 with the more accurate critical parameters.Google Scholar

    It is worth making a few technical points about the relevant length scales in this system. Traditionally, in the study of critical phenomena, two length scales are identified: first, there is the range of the direct pair correlation function, which, given that this function falls off (to leading order) as does the ieterparticle interaction potential, is a fundamental length scale of the chemical system under study. Second, is the length over which the total correlation function decays, i.e. the correlation length ξ, and it thus measures the spatial extent over which density fluctuations remain correlated (on average), a quantity which is related to the mean domain size. As the critical point is approached, this latter length diverges while the former ‘potential interaction length’ does not. It is therefore traditional to classify phenomena occuring on the correlation length scale as ‘long-range’ and those occurring on the ‘potential interaction length’ as’ short-range’ or ‘local’ When one is interested in speciic chemical phenomena, such as a spectroscopic shift, or, as here, a vibrational relaxation rate, the ‘local’ region of interest will be the range over which the solvent environment affects the solute probe. While this range may often correspond to the ‘potential interaction length’ (here 2.5 σLJ), it need not be exactly this length; thus, we herein reserve the term ‘local’ for the range relevant to a probe molecule, which we denote ri. The local lengths chosen here, ri = 1.78 and 3.09 σLJ, correspond approximately to first and second solvation shell cut-offs, respectively, with the former being the relevant length for the vibrational relaxation rates. Additionally, as one moves away from the critical point, the correlation length becomes shorter and the ‘local’ and long-range” correlation length scales become poorly separated, if separated at all.[105] In the Leneard-Jones system pictured in Fig. 1 (T = 0.55, p = 0.30 σ-2lj), the correlation length is estimated to be ξ = 3.3 σ;LJ, [27] and only the smaller local region (ri = 1.78 σ LJ) can be considered to be of shorter range than the correlation length. However, in such intermediate cases, i.e. where the local and long-range’ length scales are not well separated, it is useful to remember that the correlation length is an exponential decay constant, such that at a distance of ξ the magnitude of the mean correlations will have decayed by only 63%. Additionally, this decay constant reflects only the mean, and distributions in the domain sizes may exist. Indeed, as noted above, the computed distribution of local densities at the state point shown in Fig. 1 suggests that significant ‘local’ inhomogeneities exist on both the length scales ri = 1.78 and 3.09 ξLJ, even though ξ = ri in the latter case.Google Scholar

    Note that on the very short, first-solvatioe-shell length scale (ri = 1.78 σ-LJ), the density inhomogeneities persist to bulk densities well below the critical density, such that the mean local density on this short length-scale still exceeds the bulk value at very low densities (Fig. 2a). At these very low densities, short-range local density enhancements arise as a result of the non-idealities of the system, that is, from the intermolecular interactions. As the bulk density approaches the critical value, there is a crossover to a region in which the local density enhancements arise, at least in part, as a result of critical fluctuations and the concomitant long-length-scale density inhomogeeeities, by the preferential sampling mechanism described in the text. Clearly, the larger the local radius, the more important will be the critical fluctuations in causing the local density enhancements, and thus the more localized these enhancements will be to the critical region of the phase diagram. Unfortunately, we have no method of rigorously separating the degree to which either of these two mechanisms, the preferential sampling effect due to long-length-scale density inhomogeneities and the intermolecular interaction effect, contribute to the observed local density enhancement at a given state point.Google Scholar

    Since the compressibility enters only as a response function, this view does not imply that the local density inhomogeneities are proportional to or divergent with the compressibility. See Refs. [10] and [30].Google Scholar

    Note that very near the critical point, where the local and long-range effects are well separated, it is fundamentally incorrect to ascribe the bulk compressibility, which grows large as a result of long-range fluctuations, on a local scale, that is, to a local volume element. Nevertheless, these models work relatively well.Google Scholar

    An important feature of such compressible continuum models is that they include only direct contributions to the solvent density enhancements, meaning that any predicted density enhancement represents a direct response of the compressible fluid at each location r to the solute-solvent interaction potential at that point r, and does not include indirectly induced enhancements which result because the solvent density enhancement in one volume element induces an enhancement in another volume element as a result of the long range solvent-solvent density correlations. At short ranges (i e. within the range of the solute-solvent interaction potential) it is expected that the direct contribution will dominate the local density enhancements, such that these methods will be useful in the study of local density enhancement effects. Note that it is the neglected indirect density correlations which give rise to divergent partial molar volumes as the critical point is approached, and thus these compressible continuum models are inappropriate for predicting this and other diergent quantities.Google Scholar

    Note that in 2-dimensional systems the correlation length remains long further from the critical point than in 3-dimensional systems,[ 106,27] and this is why compressible regime behavior is already observed on the Tr = 1.15 isotherm of the 2-dimensional Leneard-Jones SCR This is in contrast to the experimental isotherms considered: the near-critical isotherm was at Tr = 1.01, while the high temperature isotherm was at Tr = 1.06.Google Scholar

    Explicitly, (A)Pi is where P(rNpN pi) is the conditional probability of finding the phase space configuration (rN,pN) given that the local density around the solute (or tagged particle) is pe. Specifically, where P(rN,pN,pi) is the joint probability of finding the configuration (rN,pN) and the local density pi. In the canonical ensemble this joint probability is where H is the Hamiltonian, Q is the canonical partition function, δ is the Dirac delta function, and evaluates the local density around the solute in the configuration (rN,pN).Google Scholar

    The homogeneous result will also be obtained from eq. 9 when the distribution P(pi,o) is narrow, as in homogeneous fluids, regardless of the relative time scales of the dynamic process and the local density fluctuations.Google Scholar

    Note that one could also encounter the intermediate case in which the time scale for the force correlation function decay is much shorter than that for the local density fluctuations, while the time scales for vibrational relaxation are longer than that for the local density fluctuations, and that this case is conceptually more difficult.Google Scholar
