Sequence and hot transitions in the CO2 molecule; Interference of adjacent lines belonging to different transitions as a function of temperature

Abstract

Carbon-dioxide spectra of some higher transitions in the 9-11 mu m region were studied. Spectra of the sequence ([10(0)1,02(0)1](I,II)-00(0)2) and hot (01(1)1-11(1)0) bands were calculated as a function of temperature. The positions of the re-vibrational transitions and their intensities were determined as a function of temperature. For lines in hot and sequence transitions whose positions are close to some of the regular lines ([10(0)0,02(0)0](I,II)-00(0)1)(1) absorption coefficients of adjacent lines were calculated as functions of line center distances and temperature. The resulting values of the absorption coefficient for conditions of constant pressure or constant volume were determined.
