Paper Abstract

This paper evaluates pulsed photolysis techniques for studying gas-phase radical-molecule reactions that are important in atmospheric chemistry. Reactions of OH are discussed. The pulsed photolysis-pulsed laser induced fluorescence (PP-PLIF) technique is described and compared with other detection techniques. As an example of application of this technique the kinetics of the OH reaction with Methyl Vinyl Ketone (MVK) and Methacrolein (MACR) over the temperature range 232-378 K are presented. Measurements of the UV absorption cross sections of MVK and MACR over the wavelength range 190-450 nm using a diode array spectrometer are also described. These data are used to calculate the tropospheric lifetimes of MVK and MACR.
