The use of coherent optical transient spectroscopy to study collisional processes in flames has been considered. A short discussion of the density matrix equations is used to illustrate transient phenomena of possible interest. Characteristic times that arise for such phenomena are calculated for a variety of flame conditions, and it is concluded that both dephasing and energy decay rates for electronic and ir transitions in selected species may be measured. Available excitation sources and transient measurement techniques are examined and found suitable for making such measurements.
