Abstract
SPECTROSCOPIC study of flames, particularly those of hydrocarbons, has revealed abnormally strong emission from their reaction zones1. The radicals produced during the combustion process itself such as OH, CH and C2 all show the effect and so do the non-resonance lines of added impurities such as iron and lead. Excitation energies up to 173 kcal./mol. have been observed but the processes responsible have remained obscure.
