摘要：

The authors describe how a low-cost teaching interferometer has been modified for use as a time-resolved instrument to study the infrared vibrational chemiluminescence of the products from atom-radical reactions and molecular photodissociations. This technique allows the entire temporal evolution of the emission spectrum to be obtained from a single interferometric scan, with spectral and temporal resolutions of 2 cm-1 and 3 mu s respectively. Illustrative results are given for discharge-flow studies of laser initiated atom-radical reactions, where product emission from highly vibrationally excited CO2 and HF is observed, and for emission from vibrationally excited products of the infrared multiple-photon dissociation of halocarbon molecules.
