This is appropriate for a magnetic dipole transition moment carried
by the magnetic moment associated with the overall rotation of the
molecule, and is proportional to J.
Parameters
Strength
Rotational magetic moment in units of the nuclear magneton.
Note that the relative intensity is proportional to the
square of this value.
Note: This implementation
has changed since version 5.3.335, with the main change being the
switch to units of nuclear magnetons from Bohr magnetons.
