experimentally and by simulating the structure of premixed laminar flat atmospheric H 2/O
2/N 2 flames of different initial compositions. The concentration profiles for stable
compounds (H 2, O 2, and H 2 O), H atoms, and OH• radicals in flames were measured by
molecular-beam sampling mass spectrometry using soft electron-impact ionization. The
experimental data thus obtained are in good agreement with the results of simulations in …
