Abstract
From gas-phase and matrix-phase i.r. spectra and liquid-phase Raman spectra a complete assignment is derived for the vibrational fundamentals of 1 H-trifluorocyclopropene- d 0 and d 1. For the undeuterated molecule the frequencies (in cm −1 and approximate characterizations of the fundamentals are: ( a′) 3157 (CH stretch), 1793 (CC stretch), 1404 (CC stretch), 1160 (CC, CF stretch), 993 (CH bend), 854 (CC, CF stretch), 764 (CF 2 stretch), 613 (CF bend), 500 (CF 2 scissors), and 281 (CF 2 rock); ( a″) 1103 (CF 2 stretch), 788 (CH wag), 570 (CF wag, CF 2 torsion), 380 (CF wag, CF 2 torsion), and 204 (CF wag, CF 2 rock). All fundamentals of the undeuterated molecule and all but one of the deuterated molecule are directly observed.
