Structure and Intermolecular Dynamics of Carbon Disulfide/Alcohols Binary Solution
We investigated the intermolecular vibrational motions of several carbon disulfide/alcohols binary solutions by using Raman-induced Kerr-effect spectroscopy (RIKES). The intermediate decay components that is assigned to the CS2 polarizability fluctuations induced by the intermolecular collision, showed dependence on the volume concentrations of alcohols. This behavior is very different from CS2/hexane binary solutions. The reduced spectral densities for fast intermolecular motion were obtained from the time-domain signal. The trend of spectral changes upon dilution were similar to that for CS2/alkane binary systems,. These results suggest that CS2 molecules would be mainly localized in the non-polar domains formed by alcohol clusters.
