Abstract:
We report the first use to our knowledge of the anomalous fluorescence of pyrene to determine flame temperature. Vapor-phase pyrene was injected into fuel-rich ethylene/oxygen flames at 80 Torr. The relative laser-induced (S(2) --> S(0))/(S(1) --> S(0)) emission was monitored as a function of height above the burner and compared with the temperature profile as measured by thermocouples and sodium D-line reversal. The agreement between the ratioing technique and the flame-temperature profile demonstrates the potential of the method.
