✦ Synopsis

Abstract

The rate constant for the reaction
has been determined by means of vacuum ultraviolet flash photolysis and time‐resolved kinetic spectroscopic observations of the 1504‐Å absorption band of CH~3~. The measurements made using three different sources of methyl radicals (azomethane, dimethylmercury, and ketene‐hydrogen) were in accord and yielded a value for the rate constant of k~1~ = (9.53 ± 1.17) × 10^−11^ cc molec^−1^ sec^−1^. A detailed error analysis is presented. The f‐value for the 1504‐Å band of CH~3~ is determined to be (2.5 ± 0.7) × 10^−2^.
