It is a pleasure to introduce and commend this volume about photochemistry by my one-time student, my colleague, and friend, Paul Suppan. We shared for many years, first at the University of Sheffield and then at the Royal Institution in London, our fascination with chemical reactions induced by light—electronic flash lamps in the early days, lasers later. This account of photochemistry continues the enthusiasm and talent for clear exposition that Dr Suppan has always shown. It is a notable addition to the literature of photochemistry and will be welcomed by students and research workers alike.
