Determination of N-, H- and O-Atom Densities in N2-H2 and in N2-O2 Gas Mixtures by Optical Actinometry in Flowing Microwave Discharges and by NO Titration in Post-Discharges

Densities of N, H and O atoms have been determined in flowing microwave discharges by optical actinometry and by NO titration for N atoms in the post‐discharge. Two N2–xH2 and N2–xO2 gas mixtures have been separately studied in the same discharge conditions: 0
