Far infrared laser magnetic resonance (FIR-LMR) spectra of CF3, CHF2,
and CH2F radicals were observed in the 300-800 mu m wavelength region
in the reactions of F atoms with a series of different hydrocarbon and
partially fluorinated hydrocarbon molecules. To identify the carriers
of the observed resonance patterns and to exclude or identify contami
nation of the spectra by additional resonances from other paramagnetic
species, numerous chemical tests were developed and performed. With o
ptimized sources and the chemical tests in hand, many spectra could be
unambiguously attributed to CF3, CHF2, and CH2F, respectively. The pr
esent study reports the first gas phase detection of CHF2 radicals in
their ground electronic state.
