 Title: INFRARED AND MILLIMETER SPECTRA OF METHYLAMINE Creators: Lees, R. M.; Lewis-Bevan, W.; Sastry, K. V. L. N.; Pitre, J. S.; Noble, T. J. Issue Date: 1985 Publisher: Ohio State University Abstract: The high resolution spectrum of the C-N stretching band of $CH_{3}$NH$_{2}$ has been obtained from 900 to $1100 cm^{-1}$ at $0.004 cm^{-1}$ resolution using a Bomem Fourier transform spectrometer. In addition, the millimeter wave spectrum of $CH_{3}$NH$_{2}$ has been investigated in the 60-250 GH2 region to fill in gaps in previously reported Q branches and to explore more fully the ground state rotation-torsion-inversion energy level structure at moderate J and K. With accurate ground state combination differences established from the microwave results, it has been possible to assign a number of low K infrared P and R branches for the stronger a-component of the inversion doublets. It is hoped to identify the weaker s-components of the doublets in order to determine the effects of vibrational excitation on the barriers to inversion and internal rotation, and also to refine and extend the set of molecular parameters describing parallel a-type transitions.
