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.
