Abstract:

Single collision vibrational excitation probabilities ere measured on treated polycrystalline gold plane and wire surfaces. For cyclobutene, strong collider behavior obtains below 600 K. The energy transfer efficiency is greater than that on a seasoned silica surface. The energy transfer efficiency declined above 600 K to a quasi-constant value in the range 900 K - 1150 K. This may be evidence for surface mobility. Unlike cyclobutene, and earlier studies of nitromethane on silica surfaces where reproducible non-catalytic behavior could be attained, nitromethane on gold showed apparent surface sensitivity which the various conditioning treatments failed to repress.
