Infrared Spectra of Crystalline CD3Cl and CD3Br

Abstract

Infrared spectra have been obtained for deuterated methyl chloride and bromide. The region covered includes all fundamental vibrations, many of which showed splittings similar to those observed for the normal methyl halides. [See D. A. Dows, J. Chem. Phys. 29, 484 (1958).] Assignments are presented, and librational frequencies in the methyl halides are summarized.
