Abstract

Absorption spectra for the 12B1- X̃2A1 transition of the phenyl radical have been recorded using the technique of cavity ring-down spectroscopy. The radicals were produced by an electric discharge through Ar/C6H5Br mixtures and cooled by supersonic expansion. Partially resolved rotational structure was observed for the 000, 901, and 1001 bands, and excited state rotational constants were derived from these data. For the 901 band, homogeneous line broadening was indicative of an excited state lifetime of 96 ps.
