摘要
Infrared spectra of (CF3)2CH2 and (CF3)2CD2 in the gas phase and Raman spectra of gaseous and liquid specimens have been recorded. An assignment of the spectra is given for a C2v model and based on Raman polarization data, gas phase band contours, isotopic shifts and a normal coordinate analysis which is reported in the subsequent paper. Furthermore several fundamentals of (CF3)2CHD have been observed and new 1H and 19F NMR data have been collected. The vibrational spectra prove that strong coupling of CH and CD bending models with CF3 and CO stretching vibrations occurs. © 1979.
