The o-fluorobenzyl radical was produced in a jet from o-fluorotoluene and vibronically excited with a carrier gas (He) in a corona-excited supersonic expansion using a pinhole-type glass nozzle. The vibronically resolved emission spectrum of the jet-cooled o-fluorobenzyl radical in the D-1 --> D-0 transition has been recorded with a long-path monochromator in the visible region. The spectrum was analyzed to obtain accurate electronic transition and vibrational mode frequencies in the ground electronic state by comparing with those from an ah initio calculation as well as those of o-fluorotoluene.
