“…We have, in addition, taken advantage of recent experimental [Dodd et al, 1996] and theoretical [Duff and Sharma, 1997a] work on the vibrational relaxation of NO by O and on the reaction of N(4S) atoms with NO [Duff and Sharma, 1996Sharma, , 1997b] to update the chemical kinetics scheme. The Einstein A coefficients and the energies of the rotation-vibration levels of NO were taken from the work of de Vivie and Peyerimhoff [1988] and Amiot [1982], respectively.…”

“…19 Process ͑1͒ could be observed for vϭ20, 21, and 22, where the energy defect is Ϫ49, Ϫ18, and ϩ14 cm Ϫ1 , respectively. 20,21 Here a positive number indicates endoergicity, whereas a negative number indicates exoergicity. In addition to vibrationally inelastic channels, vibrationally elastic energy transfer was recorded for vϭ22 and 21.…”

“…Spin-orbit changing transitions ( 2 ⌸ 1/2 → 2 ⌸ 3/2 ) could not be observed in the vibrationally inelastic channels, although they are energetically accessible for the vϭ20 and 21. 20 The distributions are ͑peak͒ normalized to show differences in their shapes. For comparison, the solid line shown in the figure is the result of a quadratic fit to the average of the vibrationally elastic data of the upper panel.…”

Our lack of understanding of the factors that compensate energy defects in near resonant V-V energy transfer constrains our ability to accurately predict resonance widths and, thus, the overall importance of such processes. We have carried out one of the first truly state-to-state measurements of near resonant V-V energy transfer under single collision conditions, employing the crossed molecular beams, stimulated emission pumping technique. We have varied the energy defect ⌬E for the process: NO X 2 ⌸(v)ϩN 2 O(0,0,0)→NO X 2 ⌸(vϪ1)ϩN 2 O(0,0,1), by changing the prepared vibrational state from vϭ22 (⌬Eϭϩ14 cm Ϫ1 ) to vϭ21 (⌬EϭϪ18 cm Ϫ1 ) to vϭ20 (⌬EϭϪ49 cm Ϫ1 ). Changes in the energy transfer efficiencies and rotational distributions of vibrationally inelastically scattered NO with energy defect both strongly suggest that molecular rotation ͑both of NO and N 2 O͒ is responsible for compensating the energy defect. Furthermore it appears that relative translation is ineffective in compensating the energy defect. A ⌬J NO ϳ⌬J N 2 0 approximation also appears valid.

“…The B(5)←X (20), B(4)←X (19), B(3)←X (18), as well as B (2)←X (17) vibronic bands were used to this end. By installing a KDP doubling crystal, the B(1)←X (6), and B(0)←X(5) bands could also be reached. The laser induced fluorescence ͑LIF͒ was collected by a quartz F/0.7 lens system and imaged onto a solar blind phototube ͑Hamamatsu 166UH ® ͒.…”

The authors present a new experimental method for measurement of collision-free infrared radiative lifetimes for single quantum states of a vibrationally excited sample. This method provides a more direct route to the infrared Einstein A coefficients than has been previously possible. Results for NO͑X 2 ⌸, vϭ21 and vϭ7͒ are presented. Comparison to results of ab initio calculations shows excellent agreement. A controversy regarding the relative intensities of first overtone and fundamental emission intensities in NO is laid to rest. The most complete least squares analysis of existing data was carried out to derive the electric dipole moment function ͑EDMF͒ to an accuracy of Ϯ0.02 D between 0.9 and 1.7 Å.
