Metal oxides are omnipresent and thus attract considerable attention with regard to various technologically important aspects. Presently, the most important applications are related to heterogeneous catalysis. A necessary— but not necessarily sufficient—condition for unravelling the fundamental principles in this complex field is to analyse in detail chemical reactions taking place at oxide surfaces.

Unfortunately, the experimental investigation of this class of materials represents a formidable problem since their surfaces often exhibit a large density of defects and are not easy to prepare. In case of ZnO, for example, the number of papers providing results from vibrational spectroscopy on single crystal surfaces is extremely small.
