β¦ Synopsis
Penning iooizafion or N2 by mernstabie Ne('P& atoms has been studied bp obsewing the laser-induced excitation spectrum oTNf(B','; +X22;) in a nrcm nflerglow. Tbe product ions NT (XI u"= O-3) were found 10 be vibrolionally more excited than predicted using Fran&-Condon hclors for the NT (X '2; ) -N,(X "; ) ionization process and the population enhancement is attributed IO auroionization.

The quenching kinetics of N,(B3ng, u),have been determined in a low-prcwre flow system in the abscncc of N atoms. Individual vibration?1 levels of the B staic were populated by laser pumping (firsr-positive bands) of N?(A31G) molecules. The latter were created upstream by energy transfer from Ar met
Tie-resolved fluorescence laser-induced spectroscopy was used to examine the quenching of the vibrational levels v = 0 and u = 1 of N;(B \*C:) by N2\_ The rate coefficients of the quenching reactions are found to be constant over the tempera ture range 300-500 K. The quenching constant for the u = 1
