The study of E- E energy transfer between CO(a 3Π, ν′) and NO(X 2Π, ν″ = 0) in beams

Abstract

The formation of NO(A,ν) and NO(B,ν) was investigated from the reaction CO(a, ν′) + NO(X, ν″ = 0) in a beam-beam configuration. The nascent rovibrational distributions of NO(A, ν = 0–2) and NO(B, ν = 0–2) were determined from NO(A → X) and NO(B → X) emissions by means of spectral simulation. The branching rate of NO(A) to NO(B) was determined to be γ/ β = 1.3 ± 0.3 by using the total emission intensities of NO(A) and NO(B). Experiments also show that the vibrational distribution of NO(A) is sensitive to the vibrational distribution of CO(a,ν′). An electron exchange mechanism is proposed for the reaction.
