Abstract : This article has suggested a research problem which deals with identification and characterization of the vibrational features of flame combustion products which radiate intensely in the 700 to 1400 1 cm region. It was pointed out that data are needed about the vibrational modes of candidate emitters at flame temperatures and in a flame environment. To acquire these data, Raman and infrared spectroscopic techniques are suggested as the experimental means. It is proposed that candidate emitters be characterized vibrationally: (1) in their neat form, (2) in an idealized flame, and (3) in a flame in which they form naturally as a combustion product. Conventional rapid scan infrared methods are suggested for the study under each of the three conditions. On the other hand, hi-temperature rapid scan laser Raman spectroscopy is proposed as a complementary method. This unique approach to the problem promises to permit us to get vibrational data about inorganic flame species which are inaccessible by other means.
