Vibrational Energy Transfer at a Liquid Gallium Surface. Activation of Unimolecular Cyclobutene Isomerization.
Abstract
Single collision vibrational energy transfer for a canonical ensemble (T=300K) of cyclobutene molecules at a heated liquid gallium surface has been studied from 450K to 700K. Transport above the reaction threshold for iosmerization to butadiene (E sub o = 32.4 kcal/mole) was used as the criterion for efficiency of vibrational energy accommodation. The efficiency was found to fall below strong collider behavior above 625K. Evidence of surface catalysis became important below 525K. The observed behavior is reminiscent of that found previously for other liquid (Sn) and solid (Au) metal surfaces.
