Vibronic emission spectrum of jet-cooled 3,4-difluorobenzyl radical generated in corona excited supersonic expansion

Observation of the vibronic emission spectrum in the D1 → D0 transition of the jet-cooled 3,4-difluorobenzyl radical generated from 3,4-difluorotoluene with a carrier gas He in a corona excited supersonic expansion using a pinhole-type glass nozzle.
