Details: Each level is characterized by the usual asymmetric top quantum numbers
J, Ka, and Kc, and the free rotor quantum number m.
When table includes hyperfine levels, standard F = J+I quantum number is added to the labeling.
The correspondence between
m quantum number in .cat file and the vibrational torsional quantum number vt and symmetry species Γ = A or E
of C3v symmetry point group is given in the table →
| m | vt | Γ |
|---|---|---|
| 0 | 0 | A |
| 1 | 0 | E |
| -3 | 1 | A |
| -2 | 1 | E |
| 3 | 2 | A |
| 4 | 2 | E |
| -6 | 3 | A |
| -5 | 3 | E |
| 6 | 4 | A |
| 7 | 4 | E |
