Rate coefficients for the chemical reactions of CH2F2, CHClF2, CH2FCF3 and CH3CCl3 with O(1D) at 298Â K

► First determination of the rate coefficient for 1,1,1-trichloroethane with O(1D). ► Improved rate coefficients for CH2F2, CHClF2, and CH2FCF3. ► In general, O(1D) reactions are not well characterized due to experimental difficulties. ► This is the first study using our new photoreactor to examine O(1D) reactions.
