Notes:
The torsional Raman spectra of one-conformer partially deuterated derivatives of ethane, CH3CD3, CH3CH2D, CH3CHD2, CH2DCD3, and CHD2CD3 have been experimentally investigated with an improved conventional Raman spectrometer. The recorded spectra have been interpreted with a rotational–torsional effective Hamiltonian and a simple model for the torsional dependence of the molecular polarizability. The effective threefold torsional potential parameters for CH3CD3 (V3=997.72 cm−1, V6=8.45 cm−1 ) have been taken from the recent literature, whilst the following parameters were obtained for the other derivatives: CH3CH2D, V3=1007 cm−1, V6=7.3 cm−1; CH3CHD2, V3=1003 cm−1, V6=8.5 cm−1; CH2DCD3, V3=993 cm−1, V6=8.2 cm−1; CHD2CD3, V3=995 cm−1, V6=6.7 cm−1. The estimated accuracy of these parameters is of the order of ±2 cm−1.
