Abstract : A pulsed DF chemical laser has been used to excite DF molecules to their first vibrational level. Decay of the infrared DF fluorescence was used to calculate the vibrational relaxation times of DF due to collisions with itself at temperatures between 468 and 920K as well as at room temperature. The high temperature data were obtained in a laser-induced fluorescence experiment performed behind a reflected shock wave in a shock tube. The relaxation time of DF(1) due to DF collisions was measured. The rate for the reaction DF(1) + CO2(000) = DF(0) + CO2(001) rate was also measured as was the deactivation of CO2(001) by DF.
