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

Carbon-dioxide spectra of some higher transitions in the 9-11 mu m region w ere 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 po sitions of the re-vibrational transitions and their intensities were determ ined as a function of temperature. For lines in hot and sequence transition s 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 a s functions of line center distances and temperature. The resulting values of the absorption coefficient for conditions of constant pressure or consta nt volume were determined.
