[Spectral study of N2O under pulsed DC discharge].

A new equipment of pulsed DC discharge supersonic molecular beam was set up for producing transient species. Thepulsed DC discharge can be used stably under 10 kV. In data collection using software, it can be utilized as gated integrators and averagers. Using this equipment, the processes of N2O discharge were studied. The emission spectra of N2O+ (A2sigma+ - X2IIi) were obtained. From the intensity of vibrational spectra, the vibrational populations of the N2O+ (A2sigma+ ) states were calculated. Compared with other results, A states of N2O+ depart even more from a Boltzmann distribution.
