Abstract

We report the implementation of a technique for the observation of laser-initiated chemical processes using time-resolved Fourier transform spectroscopy. This technique combines state-specific creation of reagents and the high resolution and broad spectral coverage of conventional Fourier transform spectroscopy with 10 microsecond time resolution of the spectral measurement. It has been applied to the study of energy partitioning in the reactions of 0(1D2) atoms with several small molecules in the gas phase at pressures of a few millitorr. Using this technique, collisional deactivation of the reaction products can be eliminated and the initial energy distribution created by the reaction is obtained. In addition, energy transfer rate constants can be measured and secondary reactions can be identified.
