The photochemical-reaction yields after IR multiphoton excitation of CHFCl-CF2Cl are reported and evaluated in terms of the steady-state rate coefficient for reactant decay \documentclass{article}\pagestyle{empty}\begin{document}$$ k({\rm st}) = 10^{6.1 \pm 0.3} ({I \mathord{\left/ {\vphantom {I {{\rm MWcm}^{- 2}}}} \right. \kern-\nulldelimiterspace} {{\rm MWcm}^{- 2}}}){\rm s}^{- 1} $$ \end{document} The dominant primary reaction channels are α,β HCl and HF elimination, although minor pathways seem to include Cl2 elimination and other channels, which are discussed. The major uncertainty in the comparison with theoretical estimates resides in the fraction of C—F chromophore band strength which contributes to excitation. The total band strength for the range from 940 cm-1 to 1310 cm-1 is reported to be G = ∫σ(ṽ) (dṽ/ṽ) = 8.2 pm2.
