Abstract
WHILE it is generally recognized that atoms and free radicals play an all important part in combustion reactions, simple direct demonstration of the presence of a definite species is often rather difficult. The experiments described below, which record a few simple observations on the reduction of molybdenum and tungsten oxides (MoO3 and WO3) at the edges of flames, appear to provide visual evidence of the presence of hydrogen atoms in flames, and also give an indication of their relative concentrations in different flames.
