RESONANT TWO-PHOTON DISSOCIATION SPECTROSCOPY OF FeO⁺: CHARACTERIZATION OF THE ⁶ Sigma

GROUND STATE.

RICARDO B. METZ, Department of Chemistry, University of Massachusetts, Amherst, MA 01003.

We have measured several bands in a ⁶ -⁶ Sigma transition in FeO⁺ with rotational resolution. In this one-color, two-photon resonant dissociation experiment, one photon excites molecules to the ⁶ state, while the second photon dissociates the excited molecules. The spectrum is measured by monitoring the yield of Fe⁺ fragments. Results of the rotational analysis of the (⁶ _7/2, v=8, 9)-(⁶ Sigma , v=0) bands will be presented.
