Abstract
The methyl alcohol and methylamine molecules both are notable for their large-amplitude CH3 torsional motions, while methylamine has a second large-amplitude motion in the inversion or "wagging" of the NH2 group. As well, both molecules are notable in having strong infrared (IR) C-0 or C-N stretching bands which overlap well with the CO2 laser bands, and thereby provide numerous opportunities for optical pumping and FIR laser line emission. Although the torsion-rotation structure of the ground and excited state energy level manifolds is quite complex, sustained spectroscopic effort over the last decade has led to a reasonable understanding and accurate mapping of substantial portions of these manifolds. In addition to the principal species of CH3OH (1-8) and CH3NH2,(9-11) several isotopic variants of the former have been studied, including 13CH3OH (12, 13), CH3180H (14, 15) and CD3OH (16).
