Laser-induced fluorescence excitation spectra of the methoxy radical have been obtained under sufficiently high resolution in a supersonic jet expansion. The rotational structure associated with its origin band has been identified in the midst of strong overlapping rotational transitions due to the hydroxyl radical in the 31490–31700 cm−1spectral region. Rotationally-resolved A2A1- X2E spectra of the 000band of methoxy have been explicitly assigned using the nomenclature for prolate symmetric top transitions in doublet states.
