Molecule Types Symmetric Tops Transition Moments | <Prev Next> |
This is appropriate for a magnetic dipole transition moment carried by the electronic orbital angular momentum. In principle the Hamiltonian for this interaction of the electron orbital magnetic moment with an external magnetic field is:
gLμBB.LDegenerate states in a symmetric top can be
thought of as having approximately one unit of angular momentum.
To allow for the most general possible interactions, the l
dependence is not included in evaluating the matrix element, and
the Strength
parameter will be essentially gLl.

J. Chem. Phys. 89 1754 (1988) for an example
application.
Strength | Transition (dipole) moment in units of the Bohr magneton. Note that the relative intensity is proportional to the square of this value. |
