Calculation of lower electronic states of the GaO and InO molecules by the SCF-Xα scattered wave method

In the overlapping atomic spheres approximation of the SCF-X SW method in different variants (spin-restricted, spin-unrestricted, and quasirelativistic), we have calculated fragments of the potential curves for the electronic ground state (X ₂) and the lower excited states (1 ², 2 ², 2 ², 3 ²) of the GaO and InO molecules. We have calculated the spectroscopic constants (T_e, _e, _ex_e, B_e, _e, R_e, A_e) for the molecules in the indicated states, the matrix elements for electronic transitions from the electronic ground state to the excited states, the Franck-Condon factors for the transitions 3 ², 2 ², 2 ² 1 ², X ² (v, v 10). For the InO molecule, we discuss the effect of relativistic corrections on the calculated molecular constants.Translated from Teoreticheskaya i Éksperimental'naya Khimiya, Vol. 22, No. 1, pp. 11–19, January–February, 1986.
