Abstract : Two experimental studies are briefly described: An investigation of the effect of reactive atoms on the rate of vibrational energy transfer in diatomic molecules, and A study of how the instantaneous reaction rate approaches the equilibrium rate as the vibrational state population approaches high temperature equilibrium from an initial distribution containing most molecules in the ground vibrational state. Both studies were performed using a pressure driven shock tube. Observations on the hot gas immediately behind the shock front were made using laser schlieren and atomic resonance absorption spectroscopy. (Author)
