Abstract

We report the first vibrationally resolved spectroscopic study of FeO+. We observe the 0←0 and 1←0 bands of a 6∑←X6∑ transition at 28648.7 and 29311 cm-1. Under slightly modified source conditions the 1←1 transition is observed at 28473 cm-1. In addition to establishing an upper limit D0 o(Fe+-O)≤342.7 kJ/mol, our results give the first experimental measurements of the vibrational frequencies in both the ground state, v″0 = 838±4 cm-1, and the excited electronic state, v′0 = 662 ± 2 cm-1. Partially resolved rotational structure underlying the vibrational peaks has been analyzed to measure the predissociation lifetime and estimate the change in molecular constants upon electronic excitation.
