Isotope Effects on Nuclear Shielding as a Means of Studying Solute-Solvent Interactions

  • P. E. Hansen
Conference paper


The solvent structure around ammonium ions is interesting as a model not only because of the similarity to alkali ions, but also because the ammonium ion may serve as a model for ammonium groups of e.g. proteins. Recent studies of T1 relaxation times revealed a very short rotational correlation time (Perrin 1986). A finding that accentuates the interesting properties of this molecule. The water structure around ammonium ions has also been treated theoretically (Szasz 1979).
