Abstract

The infrared absorption spectrum of gaseous CF 3CFH 2 between 300 and 6000 cm −1 has been obtained with a Perkin-Elmer model 112 double-pass spectrometer equipped with CsBr, NaCl, and LiF prisms. The Raman spectrum of the liquid at −70°C has been photographed with a three-prism glass spectrograph of reciprocal linear dispersion 15 Å/mm at 4358Å. The vibrational fundamentals are tentatively assigned as follows: Species a′: 2984, 1464, 1427. 1298, 1103, 972, 843, 665, 549, 408, and 225 cm −1; species a″: 3013, 1182, 665, 539, 352, 225, and 120 cm −1. The two lowest fundamentals are taken from previous work by Danti and Wood.
