Laboratory Spectroscopy of H2O and N2O

Abstract

High resolution laboratory measurements of line positions, strengths, and pressure broadening parameters of atmospheric trace molecules are important for the analysis of atmospheric measurements. Two of the several key molecules involved in this scenario are N2O and H2O. This text describes the laboratory measurements, analysis and results of an extensive study on N2O and H2O infrared spectra. The spectra were obtained with a Fourier-transform spectrometer located in the McMath solar telescope facility at the Kitt Peak National Observatory. The spectral resolution was 0.005 cm-1 for the region below 2200 cm-1 and from 2200 to 8000 cm-1, the resolution was 0.01 cm-1.
