Abstract
The ν~5~ Raman band of CH~3~CD~3~ was photographed with a resolution of about 0.4 cm^−1^ and analysed by an iterative method, in which the peak wavenumbers of the observed and computed contours are compared directly. Precise values for ν~0~ and Δ__B__ were obtained, whereas it only could be shown that Δ__A__ is an order of magnitude smaller than Δ__B__. Some basic problems of the method of analysis are discussed.

The ν 5 fundamental (C-C stretching) of CH 3 CD 3 shows a resolved torsional structure, caused by perturbations due mainly to the linear dependence of the torsional potential barrier on the normal coordinate Q 5 . We were able to analyze this structure and to assign vibration-rotation transition wav
The lowest frequency degenerate fundamental band of CH 3 SiD 3 (v 12 ϭ 1 4 0) centered around 418 cm Ϫ1 was measured in order to investigate the vibration-torsion-rotation interactions in a symmetric-top molecule with a single torsional degree of freedom. The spectrum was recorded at an instrumental
The high resolution infrared spectra of 12 CD 3 I and 13 CD 3 I molecules have been measured in the region of the CD 3 deformation bands n 2 and n 5 using a Fourier transform spectrometer. The coupled band system n 2 , n 5 , and 2n 3 has been analyzed by taking into account the Coriolis resonances n
The overtone band \(2 \nu_{8}^{0}\) of \(\mathrm{CH}_{3} \mathrm{CN}\) around \(720 \mathrm{~cm}^{-1}\) has been measured on a Bruker Fourier transform spectrometer at a resolution of \(0.003 \mathrm{~cm}^{-1}\). Only the parallel band was observed, but due to the \(l(2,2)\) resonance, \(\Delta K=-2
