Vibrational Spectra of Trifluoroethylene and Trifluoroethylene-d1

Abstract
The infrared spectra of gaseous F2C:CFH and F2C:CFD have been investigated in the range 2—50μ. Complete and satisfactory vibrational assignments have been achieved. The a′ fundamentals of the H compound are 3150, 1788, 1362, 1264, 1171, 929, 623, 485, 232; and the a″ modes occur at 750, 555, and 305 cm—1. The corresponding fundamentals for the heavy molecule are 2347, 1767, 1323, 1200, 983, 855, 620, 480, and 228 in a′, and 612, 528, and 291 cm—1 in species a″. Tables of the thermodynamic functions for the ideal gases are given.
