Preliminary study on direct measurements and diagnostics for chemical reaction dynamics of NOx by using laser wavelength modulation spectroscopy

Studies on the kinetics of gas-phase chemical reactions currently rely calculations or simulations and lack simple, fast, accurate direct measurement methods. We developed a tunable laser molecular absorption spectroscopy system to achieve measurements such by using wavelength modulated performed online diagnostics concentration, reaction temperature, pressure change during redox ozone with nitrogen oxides (NOx) 0.1 s temporal resolution. This study provides promising diagnostic tool for studying kinetics.
