General description

Rotational absorption spectrum for the ground state of trichlorofluoromethane (Freon-11) has been measured on the part per thousand levels by volume by time-resolved THz spectroscopy. Reductive dehalogenation of trichlorofluoromethane catalyzed by Methanobacterium barkeri has been reported.

Nonresonant laser-induced multiphoton dissociation/ionization studies have been conducted for trichloromethane (CHCl3) and trichlorofluoromethane (CFCl3) at 355 nm, using time-of-flight mass spectrometry (TOFMS). The molecular ion signal was found to be missing for both these compounds, and very similar fragmentation patterns
