LASER EXCITATION SPECTROSCOPY OF THE JET-COOLED METHOXY RADICAL AMIDST HYDROXYL TRANSITIONS

Laser-induced fluorescence excitation spectra of the methoxy radical have been recorded under high resolution in a supersonic jet expansion. The rotational structure associated with the 310 band of methoxy has been identified in the midst of strong overlapping rotational transitions due to the hydroxyl radical in the 32240 - 32580 cm-1 spectral region. Rotationally-resolved A 2A1 - X 2E spectra of the 3(1)0 band of methoxy have been explicitly assigned using the nomenclature for prolate symmetric top transitions in doublet states.
