Molecules at surfaces and interfaces studied using vibrational spectroscopies and related techniques

Recent developments in the major experimental vibrational-spectroscopic tec hniques (i.e. infrared absorption, Raman scattering, high resolution electr on loss, helium atom scattering and sum frequency generation) are reviewed and illustrated with selected results. Particular emphasis is given to two important topics which have attracted much attention in recent years: (i) t he complex surface reactions taking place on technologically relevant surfa ces and interfaces, and (ii) vibrational dynamics with emphasis on energy d issipation at surfaces.
