The kinetics of the reactions CSC1+ NO+ M-CF2ClNO+ M and CFCl2+ NO+ M-CFCLNO+ M have been investigated using pulsed laser photolysis/time-resolved mass spectrometry in the pressure range 1-12 Torr and at the temperatures of 233, 298, and 333 K, using Nz as the buffer gas. The results, along with those obtained in preceding works for the homologous reactions CF3+ NO+ M-CF3NO+ M and CCl3+ NO+ M-CCl3NO+ M (refs 5 and 7), were ...
