Vibrational energy transfer between adsorbed molecules has been observed using time of flight mass spectroscopy. l,kycloheptadiene was adsorbed on a MgF2 surface at 30 K both alone and with cyclohexane, CS2 and Xe as co-adsorbates. A KrF laser was used to electronically excite 1,3-cycloheptadiene. F

β¦ Synopsis
It is shown that the excitation spectrum of neutral molecules physisorbed on a dielectric surface consists of two symmetric and two antisymmetric energy modes. The spectral functions of these modes are represented respectively by two lorentzian lines whose spectral widths are descriid by the radiative decay of the energy modes in question. Numerical results are derived for the energies of excitation and spectral widths for the rare-gas atoms adsorbed on graphite. * Issued as NRCC No. 16604-* Subsequently this paper will be referred to as I. Also equations from I will be referred to as, for example, eq. (5) of I.
