Abstract
We have recently shown that there is a barrier to the dissociative chemisorption of CH4 on Ni(111) and that the translational energy associated with motion normal to the surface (from here on referred to as the normal component) and the vibrational energy of the incident CH4 molecule are effective in surmounting it [1]. The role of translational and vibrational energy in promoting dissociation is interpreted in terms of a deformation model where the barrier arises largely from the energy required to deform the methane molecule sufficiently to allow a strong attractive interaction between the carbon and the Ni surface atoms.
