Abstract

Experimental investigations of absorption and emission spectra of the water vapor at high temperature (1800....3000K) are recorded in the region 2000 - 12000 cm^-1. Hot water vapour was produced by a Multyplaz-2500 plasma source at atmospheric pressure. Highly sensitive Intracavity laser spectrometer was used to study weak absorption spectra in around 9400 cm^-1. Emission spectra of the flame were recorded in the region 2000. ..6000 cm^-1 using the IFS-125HR Fourier transform spectrometer with spectral resolution of 0.03 cm^-1 and between 9500 and 12000 cm^-1 using the DFS-452 grating spectrometer with spectral resolution of 0.13 cm^-1. The spectra are very dense over the entire wave number regions investigated, showing in addition to water lines emission of OH and other molecules.
