Abstract
The rate constants for the reactions magnified image have been measured directly by flash photolysis and kinetic spectroscopy. At room temperature, k~3~ = (3.4 Β± 0.1) Γ 10^9^ L/molΒ·s, independent of pressure in the range of 55β400 torr, and k~6~ = (2.1 Β± 0.2) Γ 10^9^ L/molΒ·s.

Ground-state NH radicals were generated by 248 mn KrF laser photolysis of NsH4 and their concentration monitored by laser-induced fluorescence at 336 mn, at total pressures near 1 Torr and temperatures between 269 and 377 K. He, Ar, Ns and NsO were used as carrier gases. Rate constants obtained at 3
## Abstract The rate constants for the reactions of the DS radical with NO~2~ (reaction 1) and ClNO (reaction 2) have been measured using the dischargeβflow technique at 2 torr total pressure of helium. The DS radical was monitored by laserβinduced fluorescence. The reactions were found to have the
The reactions of N,O with NO and OH radicals have been studied using ab initio molecular orbital theory The energetics and molecular parameters, calculated by the modified Gaussian-2 method ( G 2 M ) . have been used to compute the reaction rate constants on the basis of the TST and RRKM theories Th
