Abstract
Atomic hydrogen has been studied in an atmospheric-pressure hydrogen–air flame by using resonant multiphoton optogalvanic spectroscopy. This technique offers excellent spatial and temporal resolution, with an estimated sensitivity at the 1-part-in-106 level. This experiment represents the first reported direct, in situ optical detection of the extremely important hydrogen radical in a combustion environment.Keywords
