Abstract
The rotational correlation function of medium-sized molecules in solution has been measured directly both by absorption [1,2], and emission techniques [3, 4]. SHANK and IPPEN [5] have described a technique based on induced dichroism which provides an attractive alternative to the above approaches. In their anisotropic absorption technique a strong, polarized, pump pulse creates a hole in the ground state distribution of orientations. The return of the orientational distribution to equilibrium is probed by a weak pulse polarized at 45° to the exciting pulse. Differential absorption of the components of the probe polarized parallel with, or perpendicular to, the excitation polarization induces a time-delay dependent transmission of the probe through an analyzer polarizer.
