The data were taken rom
(1) M. Melosso, A. Achilli, F. Tamassia, E. Canè, A. Pietropolli Charmet, P. Stoppa, L. Dore, 2020, J. Quant. Spectrosc. Radiat. Transfer 248, Art. No. 106982.
The spectroscopic parameters differ slightly from those in (2). The calculation should be sufficiently accurate for all observational purposes.
The dipole moment components were derived from that of CH3Cl determined by
(2) G. Wlodarczak, B. Segard, J. Legrand, and J. Demaison, 1985, J. Mol. Spectrosc. 11, 204;
taking into account the rotation of the inertial axis system.
