Asymmetric Top Rotational Transition Moment

This represents the interaction of the molecular rotational magnetic moment with an external magnetic field, and is typically written in spherical tensor notation as:

μ_NB.Σ_k=0..2(-1)^k((2k+1)/3)^½T¹(g_r^k,S)

Note that all the parameters have units of nuclear magnetons but published values will often use Bohr magnetons. Normally only the diagonal terms, g_r^aa, g_r^bb and g_r^cc, are determined.
