We have reinvestigated the infrared spectra of $Cl2$ in $benzene1$, using carefully controlled experimental conditions. In addition we have also studied the Raman spectrum of $Cl2$ in benzene-carbon-tetrachloride mixtures to obtain frequency shifts and intensity changes. In general these studies verify the earlier results but lead to a more detailed understanding of the interaction betweeen $Cl2$ and benzene in these solutions, particularly to an understanding of recent $studies2$ criticizing the concept of charge transfer interactions.
