Abstract : In the period of this report, vibrational energy transfer studies have been carried out with three types of molecules that fall into the energetic category: these are nitromethane, azomethane and methyl nitrite. Apart from a propensity for more complex reaction mechanisms and catalytic behavior, the energy transfer properties of energetic materials at a surface seem to follow just the behavior expected from the intermolecular potential and not that of the intramolecular or reaction potential. More stable molecules can thus suffice to delineate the energy transfer properties expected for energetic materials. The study of gas/surface energy transfer has been extended to metals, i.e. to various gold surfaces, which appear to be stronger energy transfer media than fused quartz. The behavior for cyclobutene on gold was studied up to 1250 K and strong collision behavior was found below 600 K. Extension to other metals is readily possible. The examination of liquid metal surfaces as energy transfer agents is being investigated. Tin metal is being studied. Extension to other liquids will be made. A theoretical model has been applied to the calculation of energy transfer amounts between molecules as a function of molecular size, energy level and ambient temperature.
