Vibrational relaxation of NO <i>X</i> 2Π(<i>v</i> = 1) in the temperature range 100–300 °K

Abstract

Laser-excited fluorescence measurements have given rate constants for the vibrational deactivation of NO(v=1) by NO, He, and N2, and for the V–V exchange between CO(v=1) and NO(v=1) in the temperature region 100–300°K. Relaxation was caused entirely by bimolecular collisions. Deactivation rates of NO(v=1) by H2O, D2O, NO2, CH4, C2H4, C2H6, and C4H10, and of N2(v=1) by NO and CO(v=1) by NO2 and N2O4 were measured at T=298°K.
