emission spectrum was recorded from the corona discharge of precursor 2,3,4-trifluorotoluene in a corona excited supersonic expansion with a pinhole-type glass nozzle using a long-pathmonochromator in the visible region. From the analysis of the observed spectrum, we found the evidence of thepresence of the difluorobenzyl radicals in the corona discharge of the precursor. A possible mechanism isproposed
