The NO Vibrational Fundamental Band: O2-Broadening Coefficients

The first measurements of O2broadening of NO lines is reported. For the NO fundamental vibration–rotation band, polynomial representations for this broadening at 299 K are given for Ω =32and Ω = 12eandftransitions, respectively:γ3/2(|m|) = 0.06463 − 0.00262|m| + 0.000147|m|2− 0.00000327|m|3,γf1/2(|m|) = 0.06515 − 0.00381|m| + 0.000271|m|2− 0.00000665|m|3, andγe1/2(|m|) = 0.06433 − 0.00343|m| + 0.000214|m|2− 0.00000497|m|3.These broadening coefficients are on the order of 17% smaller than the comparable coefficients found for N2broadening of NO.
