Three-photon-excited fluorescence detection of atomic hydrogen in an atmospheric-pressure flame.
By using three-photon excitation at 291.7 nm of the n = 4 hydrogen level and observing Balmer-beta radiation at 486.1 nm, hydrogen atoms in an atmospheric C(2)H(2)/O(2) flame have been detected. Other schemes for hydrogen detection were also tried, and the results are discussed.
