Abstract

A time-resolved flash photolysis I tunable diode laser absorption spectroscopy (FPITDLAS) system has been constructed to study reaction products of gas-phase chemical reactions. The use of FP to initiate the chemistry results in essentially a wall-less reactor due to the time of reaction being much shorter than the time of diffusion. The use of TDLAS allows the time-resolved detection of HC1 by monitoring individual lines in the rovibrational spectrum. While the system is being developed for study of the products of radical-radical reactions, preliminary studies involved detection of HG from reaction ofCl-atoms with organic species. The reaction Cl + C₂H₆-H Cl + C₂H₅(1) was studied to characterize the system and determine the detection limit for HC1. The rate coefficient, k1, was determined to be (5.9±0.4) x 10^-11cm³molec^-1s^-1in agreement with the recommended values. H Cl (v = 0) and H Cl (v = 1) were simultaneously measured as products of the reaction Cl + CH₃CHO-H Cl + CH₃CO (2) at 2906.247 cm^-1 and 2906.337 cm^-1 respectively. It was determined for this reaction that k₂ =(7.5±0.6) x 10^-11cm³molec^-1s^-1.
