โœฆ Synopsis

The rate constant for the HO, self reaction has been determined as a function of methanol vapor concentration at 278 K and 299 K. A molecular modulation technique was used in which HO, radicals were photochemically produced in flowing gas mixtures comprised of Cl,, CH,OH, N, and 0, with HO, monitored in the UV at 220 nm. A positive linear dependence of the second order rate constant on methanol concentration was found and this effect increased with decreasing temperature. The rate constant for the HO, self reaction can be described by

in nitrogen at atmospheric pressure and in the methanol concentration range 1 .
