Measurements of Nitric Oxide Ion Vibrational Absorption Coefficient and Vibrational Transfer to N2

The line locations absorption coefficient and quenching of NO(+) vibration in the v = 1 and v = 2 by N2 have been experimentally determined. Integrated absorption coefficients corrected for a thermal equilibrium distribution are: S sub lu(1 - 2 P15) = 420/sq.cm./atm at 2291.63/cm and S sub lu(2 - 3 R2) = 653/sq.cm./atm at 2286.72/cm. Quenching of NO(+)(v) by N2 at 297 K was found to give rates of k = 2.4 times 10 to the -12 power cu.cm./sec for NO(+)(v = 2) and k = 3.0 times 10 to the -12th power/cu.cm./atm for NO(+)(v = 1). An estimate of 3 times 10 to the -13th power cu.cm./sec was found for quenching of NO(+)(v = 2) by NO at 297 K. (Author)
