High Resolution Molecular Spectroscopy of CO2 and H2O.

Abstract

The Air Force Geophysics Directorate high resolution Michelson interferometer and high temperature absorption cell were used to study the infrared absorption spectra of CO2 and H2O. Gas samples were heated to temperatures as high as 1000 K. Over 12,000 molecular transitions were identified in the experimental spectra. Line position for these transitions have been measured with an accuracy up to 0.0004 /cm. In order to identify these molecular transitions in the crowded high temperature experimental spectra, several data analysis techniques were developed. In addition, the servo system that controls the high resolution interferometer was enhanced to increase its reliability and stability.
