Variation of N2-Broadened Collisional Width with Rotational Quantum Number for the 10.4-μm CO2 Band

Abstract
Collisional widths for the individual rotational lines of the P branch of the 10.4‐μm CO2 band have been measured using a CO2 laser as the ir energy source. Both self‐broadening and N2 broadening have been studied. An anomalously large N2‐broadened width in the vicinity of J = 34 has been observed with an indication of a similar effect for the self‐broadened width.
