Magnitudes of Rotational Perturbation Parameters

This assumes that the 3E level is not shifted from its deperturbed position by spin-orbit interactions with 3E+ or 3II states from other configurations. The Aso (calculated) values in Table 5.10, obtained from 

The operator L+ = JT1, where 1 is the electronic angular momentum, 1g, is defined with respect to the center of mass G of the molecule,
