Lines intensities of the CO 2 Σ-Σ bands in the 1.43–1.65 μ region

Abstract

The line intensities of the five Σ-Σ bands of CO 2 in the 1.43–1.65 μ region have been measured with relatively low sample pressures and high resolution (0.035–0.06 cm −1). The data are analyzed to obtain the total band intensities and dipole-moment matrix elements. At 296°K the intensity of the 3 ν 3 band is found to be 3.62 × 10 −2 cm −2 atm −1. The intensities of four bands in the Fermitetrad in order of increasing frequency are 1.15 × 10 −3, 1.14 × 10 −2, 1.12 × 10 −2, and 1.27 × 10 −3 cm −2 atm −1 at 296°K.
