✦ Synopsis
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 metastable atoms.
