Far infrared and Raman spectra of solid CH 3 F and CD 3 F have been recorded at 80 and 20 K. The lattice spectra of CD 3 F and the lattice Raman spectrum of CH 3 F are reported for the first time. Additional peaks have also been observed in the far infrared spectrum of solid CH 3 F. New splittings for the internal mode fundamentals for ν 3 , ν 5 and ν 6 are reported for both compounds, and also for ν 2 (CH 3 F) and ν 4 (CD 3 F). An assignment of the observed bands is proposed. The crystal structure has not been determined directly, but the spectroscopic evidence suggests that it is centrosymmetric with at least eight molecules in the primitive unit cell.
