| Abstract: | The vapour phase Raman spectra of the molecules HCF3, ClCF3, BrCF3, and ICF3 have been recorded at pressures of up to 1 atmosphere over the fundamental frequency regions. The Raman band contours of the e-species fundamentals have been analysed to yield first-order Coriolis coupling constants from which, together with the fundamental frequencies, e-species force constants of the general harmonic potential function have been evaluated. One force field was found for fluoroform, but two different ones were found for the molecules ClCF3, BrCF3 and ICF3. |
