Abstract

Pressure-broadened ir linewidths of nitric oxide are currently used in measurement of its concentration for studies on combustion, chemical kinetics, and air pollution.1 We have measured the self-broadened width of the R(9.5)3/2 transition in the NO fundamental band by CO laser transmittance and found a halfwidth of γ = 0.0783 ± 0.0067 cm−1 atm−1. The analysis is shown to depend on the treatment of Λ-doubling, even though the doublet spacing is less than the Doppler width. The foreign gas broadening by N2 of this transition is similarly measured, and the ratio of self-broadening ability to the broadening ability of N2 is found to be 1.30 ± 0.31.
