Vibrational Spectrum of Methanetellurol

The infrared and Raman spectra of methanetellurol have been investigated with the aid of the isotopic species CH3TeD, CD3TeH, CD3TeD. Spectra of vapor, liquid, and matrix isolated samples are presented. The spectra of the molecule are consistent with the expected Cs symmetry and resemble those of a near symmetric top molecule. Normal coordinate calculations were conducted and results are reported and compared with similar molecules. Unfortunately, repeated attempts to observe the torsional motion in both solid matrix and vapor were unsuccessful.
