Vibrational relaxation measurements in HF and DF have been obtained at intermediate temperatures by combining the laser-induced fluorescence technique with shock compression heating in a shock tube. The combination of the two techniques has several advantages it permits measurements over a wide range of temperatures, and eliminates problems of wall reactions and leaky cells at high temperatures. This method was used to obtain HF and DF vibrational relaxation data in the presence of various chaperon molecules at temperatures from 460 to above 1000K and at room temperature. Data for the V-V energy transfer from DF to various diatomics were obtained from 295 to 700K and above. Modified author abstract
