Summary

The use of a tunable diode laser spectrometer operated in second harmonic detection mode, in conjunction with a Fourier transform spectrometer, has allowed to obtain the rate constant kD of the reaction (D)NO3+NO2→NO+NO2+O2 as a function of the rate constant kC of the reaction (C) NO3+NO→2NO2. Using literature data of the kDxk±B product where k±B is the equilibrium constant for the reactions (+B, −B), NO3+NO2=M⇄N2O5+M, a value for k has also been determined. The value derived for kD using for kc (3±0.9)× 10−11 cm3 molec−1 s−1 results equal to (5.13±1.80)×l0−16 cm3 molec−1 s−1 and that for k±B equal to (2. 5′6±0.89)×1010 molec cm−3, both at 296 K. Advantages and limitations of the use of the TDL spectrometer in this study are discussed.
