Abstract: The authors obtain the Raman, IR and NMR spectra of CH3-X-H(X=O, S, Se, Te). The spectra have been analyzed on the basis of Cs symmetry, but the present observations show that the obtained spectra can be explained on the basis of C3v symmetry. Because it is in goood agreement with theoretical expectations for C3v model that four parallel type bands are polarized in Raman and have P, Q and R branches in infrared, the P-R separations of which are observed to be 40, 30 and 24 cm-1 for CH3OH, CH3SH and CH3SeH, and are estimated to be 43.2, 28.8 and 24.3 cm-1 for them respectively, on the basis of the parameters for C3v model. The observed spectra of these molecules resemble closely those of CH3-C≡N and CH3-Br, whose symmetry is C3v. In addition, the NMR spectra strongly support a C3v model for CH3-X-H.
