THE NO(A(2)SIGMA(+)) EXCITATION MECHANISM IN A N-2-O-2 PULSED RF DISCHARGE

摘要

Time-resolved laser-induced fluorescence detection of N-2(A(3) Sigma(u)(+), v) metastable and NO(X-2 Pi) and time-resolved emission spectroscopy of the gamma-band of NO have been applied to a N-2-O-2 RF pulsed discharge in order to show that the process N-2(A(3) Sigma(u)(+), v) + NO(X-2 Pi) --> NO(A(2) Sigma(+), v') + N-2(X-1 Sigma(g)) is responsible for NO(A) excitation in discharge systems of this kind. Highly resolved spectra obtained under such conditions have revealed that there is a non-Boltzmann rotational distribution in the NO(A, v = 0) state with a large excitation of levels J > 20.
