Abstract
The torsional vibration spectra of $(CH_{3})_{2}CHX$ and $(CH_{3})_{2}CX_{2}$ molecules, $(X = halogen atom)$ were investigated and the barrier to internal rotation calculated. The low frequency vibrations of $CH_{3}CH_{2}Cl, CH_{3}CH_{2}$, and $CH_{3}CH_{2}Br$ were reinvestigated in the $350-90 cm^{-1}$ spectral region and compared with the spectra of deuterated species. The calculation of the potential barrier will be discussed. The torsional vibration spectra of $(CD_{3})_{2}NH$ and $(CD_{3})_{2}C = O$ will be presented. Spectra and potential barrier will be compared with the undeuterated species.
