✦ Synopsis

In order to make fall use of the possibilities presented by fiat flame burners, it is necessary to use a narrow beam of light. The factors affecting the spatial resolution and the radiation intensity are discussed, and ttle construction of a double-beam i.r. spectrometer incorporating this principle is described. The instrument has been used for the study of flat diffusion flames, and the different possible modes o/ operation are considered in relation to methane-o.xygen and ethylene-oxygen flames. For absorption work, the pre-chopped, single-beam techniqtte has been found to be the most useful. The potentialities and the difficulties o] the study of flames by i.r. absorption spectroscopy with such an instrunlent are discussed.
