Abstract
Solvent dependent Raman band studies of some carbonyl containing molecules have been carried out in chlorobenzene (CLB) and chloroform (CLF) solvents. The variation of bandwidth with the solvent concentration was discussed using different mechanisms. The vibrational and reorientational correlation times were studied corresponding to solvent concentrations. The reorientational correlation time follows with the liquid viscosity in molecules under study. It reflects about the nature of solvent molecules hindering to the orientational motion of solute in liquid solution.
