Abstract
Raman scattering (100 to 3000 cm− 1) and infrared absorption spectra (500 to 11 500 cm− 1) of CD3CD2CD3, CD3CHDCD3, and CHD2CD2CD3 are reported and analyzed. The major features of the overtone region can be explained on the basis of coupling between overtones of C–H stretching vibrations and CHD deformation vibrations. Fermi resonance coupling interactions become stronger with increasing overtone number up to Δv CH=3. This coupling is analyzed for CD3CHDCD3. Implications for C–H stretching frequency and C–H bond length correlation are discussed.Keywords
