EXCITED-STATE ABSORPTION-SPECTRUM OF F2+ CENTERS AND THE H2+ MOLECULAR-ION MODEL

Five principal transitions, three of which from the first excited state, have been measured in absorption for the F2+ center in KF. With one significant exception, these data are in essential agreement with predictions of the simple H2+ molecular-ion model. The measurements were made by way of a novel optical pumping technique, which allows for direct, accurate determination of band strengths and shapes, even in the presence of strong overlapping absorptions by other species. © 1979 The American Physical Society.
