Surface Reactions gives case studies of mechanistic studies of molecular transformations on metal surfaces. It focuses on surface chemistry and the way the tools of modern ultrahigh vacuum techniques can be utilized to delineate details of chemical reactions on metal surfaces. It presents a uniform, complementary set of case studies and, although each chapter stands on its own, as a whole the book presents a uniquely integrated picture. The reader will gain a comprehensive understanding of the methods used to understand surface reactivity and a broad understanding of the principles.
