Zusammenfassung:Raman displacements, semiquantitative relative intensities, and precise depolarization factors for trichloromethane, fluorotrichloromethane, and bromotrichloromethane were obtained in the liquid state. Several overtones and combination bands hitherto unreported are given and frequency assignments are made. The Raman data in the literature for CCl3H, CCl3D, CCl3F, CCl4, and CCl3Br in the liquid state have been collected and the probable values ascertained. Force constants in modified valence force potential functions containing all possible interaction constants were calculated for the five molecules.
