Laser cooling and magneto-optical trapping of molecules typically involves multiple transitions driven by several laser frequencies. We analyze how magneto-optical trapping forces depend on the angular momenta, Fl and Fu, and the g-factors, gl and gu, of the lower and upper states. When F l > F u ?> the polarizations must be reversed relative to cases where F u ≥ F l . ?> The correct choice of circular polarization depends on the sign of gu but not on the sign of gl. If gu is zero there is no…
