Microwave Spectra of Molecules of Astrophysical Interest: XXV. Methylamine

Published

Author(s)

Vadim V. Ilyushin, Francis J. Lovas

Abstract

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.
