The Cover shows various hydrocarbon species generated during methane and ethylene adsorption and subsequent thermal dissociation on Ru(0 0 0 1). In their Full Paper, H. Kirsch et al. characterize the decomposition pathways of both gasses employing vibrational sum frequency generation spectroscopy and find several previously unobserved intermediates via their CH stretch vibrations. The existence of these intermediates, and their differing thermal stabilities for the two systems, is straightforwardly rationalized by surface site blocking by adsorbed carbon and hydrogen. These results fill in significant gaps in previously proposed dissociation pathways for both gasses and highlight the potential of high resolution spectroscopy of interfacial CH stretch containing moieties in understanding catalytic processes involving hydrocarbons. More information can be found in the Full Paper by H. Kirsch et al. on page 728 in Issue 4, 2016 (DOI: 10.1002/cctc.201501046).
