Doppler-Limited Spectrum of High Temperature Water Vapor in the 3000 to 4000 cm(-1) Region.

Abstract

The absorption spectrum of water vapor has been recorded at very high temperatures (approximately 1200 K) in the 3000 to 4000 1/cm region with Doppler-limited resolution using a tunable difference-frequency laser spectrometer. This region encompasses the strong OH stretching fundamentals and the bending overtone. The higher rotational and vibrational energy levels observed here are expected to lead to extended theoretical models of H2O which are necessary to predict and analyze spectra from high temperature combustion processes.
