Observation of vibronic emission spectra of difluorobenzyl radicals: Jet-cooled 2,5-difluorobenzyl radical

Spectroscopic observation of jet-cooled 2,5-difluorobenzyl radical produced from 2,5-difluorotoluene seeded in a large amount of inert carrier gas He and vibronically excited in a corona excited supersonic expansion using a pinhole-type glass nozzle.
