Vibration Spectra and Assignments of 1,1,2,2-tetrafluoro cyclopropane- d0, d1 and d2

Abstract

From i.r. and Raman spectra complete assignments of fundamental vibration frequencies have been obtained for c-C3F4H2, c-C3F4HD and c-C3F4D2. For the undeuterated molecule the assignments are: (a1) 3022, 1526, 1366, 1076, 771, 489 and 291; (a2) [1344], 913, 435 and 194; (b1) 1204,1204, 1026, 828, 618 and 465; (b2) 3115, 1254, 871, [435] and 177 cm−1. The 1344 cm−1 value is tentative, and the 435 cm−1 value is derived from the assignments for the d1 and d2 molecules. A frequency in the 1450–1600 cm−1 region, due principally to ring breathing, has been shown to be a characteristic group frequency for fluorocyclopropanes and related ethylene oxides.
