The development of high-energy DF chemical lasers at operational temperatures below 300 K has prompted the need for detailed kinetic studies of DF in this low-temperature regime. The purpose of this memorandum is to report the investigation of DF relaxation measurements at low temperatures using the laser excited vibrational fluorescence technique. The authors have extensively studied the DFv1 self-relaxation rate and the HFv1 quenching rate by DF at 198, 209, 232, 264 and 296 K. In addition to the above measurements, upper limits have been established to the DFv1 quenching rate in the presence of argon at each temperature.
