Abstract
Polarized Raman measurements have been made for the totally symmetric vibration bands of a series of halogenโsubstituted methanes in the liquid state at room temperature. The effect of polarization mixing due to divergence was examined experimentally and eliminated. The observed systematic variations in depolarization ratio are discussed in connection with the bond polarizability theory.
