✦ Synopsis

Raman and far-infrared spectra of crysmlline fluoroform at temperatures between 20 and 106 K have been recorded. There is no evidence for any solid-state phase transitions, nor for hydrogen bondin&. The rich larice spccrm and crysral field splittings suggest that the unit cell is rather large, and possible structures are discussed. l_ htroduction 2. Experimental As part of a study of the solid haloforms, Raman and infrared spectra of solid fluoroform CHF3 have been recorded. Previously completed work includes a structural determination of the three solid phases of bromoform [ 11, Raman and infrared studies of these phases [2], and a spectroscopic investigation of solid chloroform [3], which has only one stable crystal modrfrcation [4].
