TheA2Πustate of O2+ was earlier established as an inverted state contrary to previous assumptions. The rotational analysis of a few more bands of theA-X system of O2+ has now been completed. These studies show that the spin-orbit coupling constantA in theA2Πustate gradually varies with the vibrational quantum numberν and is found to be positive forν⩾6. It has also been observed that the spia-rotation interaction is not negligible in theA2Πustate. The spin splitting constantγ is reported for various vibrational levels of this electronic state.
