In the preceding chapters I have concentrated on observations relating to the spectra of flames and related sources. Now the time has come to talk of many things, in fact to" stick my neck out" and give my opinions on the interpretation of the observations and their bearing on theories of chemical reaction processes in flames and on the detailed structure of the reaction zone. As usual, the arrangement of the chapter is similar to that in the previous edition, but ideas have matured considerably and this has led to much detailed revision. As pointed out in Chapter I, no single tool can be an open sesame to all combustion problems i major developments in mass spectrometry and gas chromatography have recently added to our knowledge of the intermediate species which occur in flames and slow combustion, but in a book on Flame Spectroscopy it is natural for me to weight the spectroscopic data rather highly. The visible and ultra-violet light from flames represents a very small fraction of the energy released, and this radiation comes from a very limited selection of electronically excited molecules, but despite this the emission of light is the most distinctive single property of flame and must surely be capable of giving much information about what is happening. Astronomers do not hesitate to use the spectrum of the extremely faint light from the stars to make pronouncements about their composition, temperature, structure and motion; a flame is, by comparison, a convenient and simple source in which many of the variables can be controlled at will, and its spectrum should be capable of giving quite detailed information on the state of the flame gases.
