ResumoWhen the products of the interaction between methyl fluoride and F atoms, produced in a microwave discharge, are frozen in a large excess of argon at 14 K, infrared absorptions previously assigned to CH2F, HCF, and [CH3F+HF] appear. The reaction of F atoms in the solid also leads to the appearance of prominent absorptions of the [CH2F+HF] hydrogen-bonded complex. At higher F-atom concentrations, absorptions of CH2F2 and of [CH2F2+HF] become prominent. A revised assignment is proposed for CD2F. At wavelengths shorter than 280 nm, CH2F photodecomposes, producing CF. The photodecomposition of [CH2F+HF], which has a somewhat higher energy threshold, leads to the appearance of [CF+HF]. A detailed discussion of the chemical reactions and photodecomposition processes characteristic of these experiments is presented.
