Semiempirical investigation of perturbations of the g factors of electronic-vibrational-rotational levels of hydrogen: III. The r(3)Pi(-)(g) s(3)Delta(-)(g) states of the H-2 and D-2 molecules

摘要

The g factors of rovibrational levels of the (4d)r(3)Pi(-)(g) and (4d)s(3)Delta(-)(g) states of the H-2 and D-2 molecules have been obtained for the first time. These values were found within the nonadiabatic model taking into account the interaction of the 4d pi(3)Pi(g) and 4d delta(3)Delta(g) states in the pure precession approximation using semiempirical values of the expansion coefficients of the wave function in an adiabatic basis, which was obtained for the first time for the states of the triplet 4 d complex of terms of the hydrogen molecule, and the results of numerical calculation of the overlap integrals of the vibrational wave functions of these states. It is established that the interference effects of the interaction between the 4d pi(3)Pi(g) and 4d delta(3)Delta(g) states lead to significant ( up to 7 times for the r(3)Pi(-)(g) state of the H-2 and D-2 molecules and 70 and 8 times for the s3 Delta(-)(g) state of the H-2 and D-2 molecules, respectively) differences between the nonadiabatic values of the g factors and the corresponding adiabatic values. It is found that the perturbed values of the g factors are much closer to the values corresponding to the case of Hund's d coupling of angular momenta than to the values corresponding to the b coupling. It is established that the perturbations of the g factors of rovibrational levels of the states of the 4d complex of terms are much greater ( up to 2 times for the 3 Pi(-)(g) states and 350 times for the (3)Delta(-)(g) states) than the perturbations of the same characteristics for the 3d complex of terms of the hydrogen molecule with the same vibrational and rotational quantum numbers.
