    Notes: Abstract The Fourier transform infrared (FTIR) spectrum of the CO-stretching fundamental band of CD3OH has been recorded at a resolution of 0.002 cm-1. Assignments are reported for 35 subbands in the n = 0 ground torsional state, covering K = 0 to 9 for all torsional symmetries plus K = 10 A, and 12 assorted A and E subbands in the n = 1 first excited torsional state ranging from K = 0 up to K = 5. The subband wavenumbers have been fitted to J(J + 1) power-series energy expansions to obtain subband origins and a compact representation of the spectral observations. With the use of known ground-state energies, CO-stretch energy term values have been determined and tabulated. Least-squares fitting of the subband origins to a fourth-order Hamiltonian model for the CO-stretch mode is discussed.

    Far infrared spectrum of methylamine (1987)
    Springer
    International journal of infrared and millimeter waves 8 (1987), S. 803-825

    Notes: Abstract The far-infrared (FIR) spectrum of CH3NH2 has been studied in the 25–125 cm−1 region at a resolution of 0.005 cm−1 with a BOMEM Fourier transform spectrometer. All of therR branches with K rotational quantum number from 5 to 13 have been identified for A-a and E-a torsion-inversion symmetries in the ground torsional state, as well as some branches of A-s and E-s symmetries and some in excited torsional states. The observed branches have been fitted to series expansions in order to determine the branch origins.
