Transient Behaviors in Chemical Reactions: Nanosecond Infrared Spectroscopy, Chemically Pumped Visible and Near-IR Lasers
Abstract
An excimer laser with pulse duration of 28 ns FWHM and average power at 248 nm of 530 mj per pulse was purchased and used as a photolysis source to accompany an existing nanosecond infrared spectrometer. With this system, transient molecular species with lifetimes as short as ten nanoseconds can be investigated. Gaseous CF31 was photolyzed to produce CF3 radicals whose infrared spectra around 1250 wavenumbers were taken at selected delay times. At very short delays highly vibrationally excited radicals are found, and a measure of vibrational relaxation rates can be made.
