Abstract : Single collision activation of the 'energetic' species azomethane at a hot seasoned fused silica surface was studied. Excitation above the critical threshold (E sub 0 approx. 50 kcal/mole) was monitored by subsequent homogeneous decomposition. The collisional efficiency was studied over the range 700K to 875K. Energy transfer efficiency is discussed and compared with values for other substrate molecules of comparable size and polarity. The data emphasize the uncertainty that still prevails with respect to the values of the Arrhenius parameters for this system. (Author)
