Line intensities of CO 2 in the 2·7 micron region

Abstract

Individual line intensities have been measured at 0·025 cm −1 resolution and low pressures for the two strong Σ-Σ bands of C 12O 2 16 near 2.7 microns, as well as for their associated Π-Π hot-bands. Values of the rotationless dipole-moment matrix elements and vibration-rotation interaction coefficients are reported along with total band intensities. Results for the latter in cm −2 atm −1 at 296°K are: 25·7, 1·96, 39·3 and 3·23 for the 02 01-00 00, 03 11-01 10, 10 01-00 00, and 11 11-01 10 bands, respectively.
