Infrared Absorption by CO2 and H2O

Abstract

Spectral transmission data for CO2 are presented between approximately 495 and 835/cm for a variety of samples of CO2 mixed in dry air. Sample parameters cover a wide range of pressures with the temperatures near 310 K. The spectral resolution varies from approximately 0.4 to 0.6/cm. Also included are data on the continuum absorption by H2O between 300 and 825/cm. Experimental data on H2O absorption are compared with data calculated on the basis of several theoretical line shapes. The H2O continuum absorption decreases more rapidly with increasing temperature than is predicted by line-shape theories.
