利用拉曼诱导克尔效应光谱（RIKES）研究了几种二硫化碳/醇二元溶液的分子间振动。中间衰减成分，这是分配给CS2极化率波动引起的分子间碰撞，表现出依赖于醇的体积浓度。这种行为与CS2/己烷二元溶液非常不同。从时域信号中获得了快速分子间运动的约化谱密度。稀释后的光谱变化趋势与CS_2/烷烃二元体系相似。这些结果表明，CS2分子将主要局限于非极性结构域形成的醇簇。
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 CS2polarizability 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 CS2molecules would be mainly localized in the non-polar domains formed by alcohol clusters.
