comments|Rotational as well as rovibrational transition frequencies
comments|were reported by
comments|(1) C. R. Markus, S. Thorwirth, O. Asvany, and S. Schlemmer,
comments|2019, Phys. Chem. Chem. Phys. 21, 26406.
comments|Data are limited to Ka = 0 and 1. Therefore, calculations
comments|for Ka = 2 should be viewed with some caution, higher ones
comments|with considerable caution. Transitions above 500 GHz should also be
comments|viewed cautiously.
comments|The dipole moment was taken from a quantum chemical calculation
comments|by

comments|2018 Icarus 299, 187.
comments|At low temperatures, it may be necessary to discern between
comments|ortho-H2CNH2+ and
comments|para-H2CNH2+. The para
comments|states are described by Ka being even, the
comments|ortho states by Ka odd.
comments|The nuclear spin-weights are 5 and 3 for ortho
comments|and para states, respectively.
