✦ Synopsis
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 state was found to be approximately twice the value of the quenching constant of the u = 0 state.

N2B3ng, Y = O-2 and N\*a"v;, Y = 0 were produced by pulsed rodiolysis af nitrogen (100-2000 torr) and fo!lowed by fast kinetic absorption spectroscopy in the second and fifth positive system. T!le rate constants for the denctivation of the species by nitrogen were found to be ~N~A,~ = 1.6i + 0.8; 2.
The quenching kinetics of N,(B3ng, u),have been determined in a low-prcwre flow system in the abscncc of N atoms.

Fluorescence excitation by a tunable dye-laser has been used for measuring the natural iifetime of the OH('ZC) radical, and its chemical lifetime in the presence of atomic hydrogen, molecular hydrogen and argon. For the 0H(2Z+, u = 0, N = 2.J = 3/2) state a natural lifetime of (0.82 + 0.04) wet was
