Abstract

Quantitative analysis of gas mixtures by infrared spectroscopy requires a knowledge of the absorption coefficients,: κν, as a function of optical path length and temperature. For the majority of pollutant gases, information is scarce or incomplete. The objective of this work was to determine absorption coefficients for CH₄, C₂H₄, CO₂, CO, SO₂, NO₂, NO, and H₂S. Measurements were made at room temperature and elevated temperatures for certain wave lengths, and κν was determined over a very wide range of optical path length, <i>x</i>. The validity of the Bouguer-Beer law was confirmed for a limiting range of <i>x</i>, and for larger values of <i>x</i>, κν decreased and was correlated as a function of <i>x</i> and <i>T.</i>
