Title: Relaxation of molecules with chemically significant amounts of energy: Vibrational, rotational, and translation energy recoil of an N sub 2 O bath due to collisions with NO sub 2 (E = 63. 5 kcal/mol)

Abstract

Single-collision quenching of highly vibrationally excited NO{sub 2} by N{sub 2}O molecules has been studied. The ground state, N{sub 2}O(00{sup 0}0), first ({nu}{sub 3}) asymmetric stretch, N{sub 2}O(00{sup 0}1), and first ({nu}{sub 1}) symmetric stretch, N{sub 2}O(10{sup 0}0), vibrational levels of N{sub 2}O were probed by using infrared diode laser techniques following pulsed dye laser excitation of NO{sub 2} to an energy E = 63.5 kcal/mol (22,200 cm{sup {minus}1}). Excitation of both the N{sub 2}O {nu}{sub 1} (10{sup 0}0) and {nu}{sub 3} (00{sup 0}1) states by collisions with high-energy NO{sub 2} is accompanied by only a small rotational and translational energy increase. In marked contrast, rotational excitation of N{sub 2}O (00{sup 0}0) ground-state molecules due to collisions with high-energy NO{sub 2} is accompanied by a large increase in translational energy.
