Low-frequency Raman spectroscopy of solid p-dichlorobenzene/p-bromochlorobezene solutions

Polarization studies of low-frequency Raman spectra of solid p-dichlorobenz ene/p-bromochlorobenzene solutions are performed at different percent compo sitions of the components. The broadening of several lines was observed in solutions containing 75% of p-dichlorobenzene. The widths of lines related to orientation vibrations around the axis with the mean inertia moment show anomalous behavior. Several additional low-intensity lines are detected. T he experimental results are explained on the basis of calculating the histo grams of solid solutions by the Din method.
