The rate coefficient of the reaction of OH with CF/sub 3/CH/sub 2/F at six temperatures in the range 255-424K was determined by means of the discharge- flow/resonance-fluorescence technique. The resonance fluorescence of OH, excited by emission from a gaseous mixture of H/sub 2/O and He subjected to a microwave discharge, was detected by photon-counting technique. The reaction was carried out under pseudo-first-order conditions with [ CF/sub 3/CH/sub 2/F ]
[ OH ] ; the rate coefficient was determined to be k=(3.9.plmin.0.6)* 10/sup -15/cm/sup 3//molecule-s at 298K; the uncertainty represents the 95% confidence limit. The temperature dependence of the rate coefficient is expressed in the Arrhenius form, k(T)=(9.9.plmin.1.0)*10/sup -13/ exp [ -(1640.plmin.150)/T ] cm/sup 3//molecule-s. - 英文摘要: --
