Linear Molecule Transition Moments
The
following types of transition moments are currently implemented
for linear molecules:
  - Spherical - electric
dipole moment in
spherical tensor form allowing its use for multiphoton and Raman
transitions in addition to normal one photon transitions.
 
  - Spin - the magnetic moment
from electron spin.
 
  - Orbital -
the magnetic moment from electron orbital motion.
     
  - Rotational
- the magnetic moment from molecular rotation
 
  - Nuclear - the magnetic
moment of
a
nucleus
