Far Infrared Laser Magnetic Resonance Detection of CF_3, CHF_2, and CH_2F

摘要

Far infrared laser magnetic resonance (FIR-LMR) spectra of CF_3, CHF_2, radicals were observed in the 300-800 μm wavelength region in the reactions of F atoms with a series of different hydrocarbon and partial- ly fluorinated hydrocarbon molecules. To identify the carriers of the observed resonance patterns and to exclude or identify contamination of the spectra by additional resonances from other paramagnetic species, numerous chemical tests were developed and performed.
