- Аннотация: In the framework of a unified physical model, employed as a basis Hund’s case ‘’c,” a quantitative description has been worked out for experimental data of term values, g factors, and lifetimes of excited B0u+ and A1u states, as well as for relative intensities in B0u+-X0g+, A1u-X1g, and B0u+-X1g transitions. The model includes a minimum number of adjustable fitting parameters: deperturbed molecular constants for both states, intramolecular interaction matrix element (eta), two electronic matrix elements of magnetic interactions (G(z),G+/-), as well as two parallel (R(e parallel-to)B0u+-X0g+, R(e parallel-to)A1u-X1g) and two perpendicular (R(e perpendicular-to)B0u+-X1g, R(e perpendicular-to)A1u-X0g+) electronic transition moments. The B0u+ state g factors and the intensity distribution over P, R, Q branches in B0u+-X1g transition was found to be most sensitive to weak heterogeneous (DELTAOMEGA = +/- 1) perturbations, and a simple analytic connection between those characteristics has been proposed. The OMEGA-doubling constant- for A1u state levels was evaluated. By transforming the responsible electronic matrix elements to Hund’s case ‘’a” basis, the A1u state has been found to be basically a 3SIGMA1 component of the B 3SIGMA(u)- state, with a small admixture (< 14%) of a 3PI1 component of the A 3PI(u) state, and a change in term notation from A1u to B1u is proposed.
