The NO vibrational fundamental band:: O2-broadening coefficients

The first measurements of O-2 broadening of NO lines is reported. For the NO fundamental vibration-rotation band, polynomial representations for this broadening at 299 K are given for Omega = 3/2 and Omega = 1/2e and f transitions, respectively: gamma(3/2)(\m\) = 0.06463 - 0.00262\m\ + 0.000147\m\(2) - 0.00000327\m\(3), g(1/2)(f)(\m\) = 0.06515 - 0.00381\m\ + 0.000271\m\(2) - 0.00000665\m\(3), and gamma(1/2)(e)(\m\) = 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 N-2 broadening of NO. (C) 1998 Academic Press.
