LASER-INDUCED FLUORESCENCE OF RADICALS PRODUCED IN REACTIONS OF HALOGENATED ETHYLENES WITH ATOMIC OXYGEN

Three new laser-induced fluorescence spectra have been observed when r eacting oxygen atoms with halogenated ethylenes such as CHFCF2, CF2CHC l, CH2CCl2, CH2CHCl, and CHClCHCl. These new spectra are similar to th ose reported previously for the vinery (CH2CHO) and CH2CFO radicals, w hich suggests that they can be assigned to other halogenated vinery-ty pe radicals. Recently Williams and Fleming assigned one of these LIF s pectra to the FCO radical; additional experiments have been done to ad dress this conflicting assignment.
