A home-made pinhole-type glass nozzle was employed to generate vibronically excited but jet-cooled benzyltype radicals from precursor 2-fluoro-4- chlorotoluene with a large amount of carrier gas He, from which the visible vibronic emission spectrum was recorded with a long-path monochromator. From an analysis of the spectrum observed, it was found that two benzyl-type radicals, 2-fluorobenzyl and 2-fluoro-4-chlorobenzyl radicals, were formed from the precursor in corona discharge. The possible pathway for the production of benzyl-type radicals that can explain the spectroscopic observation is herein proposed. In addition, the electronic energy of the D1 → D 0 transition and the vibrational mode frequencies in the D0 state of the 2-fluoro- 4-chlorobenzyl radical were determined for the first time.
