Asymmetric Top Transition Moments
The following types of transition moments are currently implemented
for asymmetric tops:
  - Cartesian -
conventional a, b or c electric dipole moment components.
 
  - Spherical - electric
dipole moment in
spherical tensor form, appropriate for multiphoton or Raman transitions.
 
  - Orbital -
the magnetic moment from electron spin, which includes residual orbital
angular momentum.
     
  - Rotational
- the magnetic moment from molecular rotation
 
  - Nuclear - the magnetic
moment of
a
nucleus
