This is appropriate for a magnetic dipole transition moment carried by the electronic orbital angular momentum.
Settings
Rank
Rank of transition - 2 (twice 1) for a normal magnetic dipole transition.
Component
Projection
quantum number of transition moment - 0 for a parallel transition, 2
(twice 1) for a perpendicular transition. For linear molecules this will normally be the
change in Λ for the transition.
Parameters
Strength
Transition (dipole) moment in units of the Bohr magneton. Note that the relative intensity is proportional to the square of this value.
