An ab initio study on some low-lying singlet and triplet states of SbO2+ and quartet states of SbO2

The first three photoelectron bands in the ultraviolet PE spectrum of SbO2, yet to be recorded, should be broad, broad and sharp respectively. The first two PE bands should consist of mainly long vibrational progressions in the bending mode. SbO2(X∼2A1)+hν→SbO2+(X∼1Σg,a˜3B2andb˜3A2)+e.
