Molecular Spectroscopy and Structure

Rotational analysis has been carried out for the first time for bands of the A2Πi-X2Πr system of the SO+ ion, as well as for newly discovered bands of the b4Σ−-a4Π transition of the same ion. At the same time, ab initio calculations were performed using the SCF method followed by configuration interaction. Theoretical results are presented as required for interpretation of the spectra. Important spin-orbit interactions are shown to occur between the four X2Πr, A2Πi, a4Πi, and b4Σ− states and neighboring unobserved states.
