Аннотация:Values and signs of Lande factors (g) have been measured for four rovibronic levels of the A (1)SIGMA(u)+ state of the Na2 molecule. Because of a very small product g-tau approximately 10(-12) s, the level crossing signal of a dispersion shape was employed using circular light polarization and mutually orthogonal excitation, observation of laser induced fluorescence, and external magnetic field directions. The effects of the b (3)PI(u)+, B (1)PI(u), and a (3)SIGMA(u)+ states on the g factors of the Na2 (A (1)SIGMA(u)+), as well as their dependence on vibrational and rotational quantum numbers, have been theoretically analyzed. An analytical connection has been found between the constants of LAMBDA doubling (q) and Lande factors of the interacting singlet states. Simple expressions have been found for estimating the effects of distant electronic states on q and the g factors without summing over bounded and integrating over continuum levels of the perturbing state.
