Microwave Spectra of Molecules of Astrophysical Interest: XXV. Methylamine



Vadim V. Ilyushin, Francis J. Lovas


The microwave spectrum of methylamine in its ground vibrational state is critically reviewed and supplemented with spectral frequency calculations derived from rotation-internal rotation-inversion analysis. The review covers frequency range from 1 GHz to 500 GHz and includes the transitions with rotational quantum number J from 0 to 30. Along with calculated frequency for each transition the lower state energy, line strength, and estimated 95% confidence limit are presented. For J?10 transitions and some J>10 transitions exhibiting large hyperfine splittings the quadrupole hyperfine structure is also tabulated.
