Abstract

We have measured the foreign-gas broadening coefficients for collisional broadening of lines in the ν₃ fundamental of N₂O by He, Ne, Ar, Kr, Xe, H₂, D₂, and CH₄. These coefficients, which give the ratio of the line-broadening ability of these gases to the line-broadening ability of N₂, can be used with recent measurements and calculations of N₂ broadening to obtain optical collision cross sections.
