Progress is reported in studies of key chemical and physical processes by which molecules in excited electronic states dissipate their excess energy. Many of these energy relaxing mechanisms and related molecular motions are so extremely rapid, especially in liquids, that they require special techniques for their study. To this end sophisticated picosecond laser systems were constructed which enable detection of transient absorption, emission and scattering events on the picosecond time scale. Spectroscopic methods are used to address two important classes of chemical problems. One is the key role played by excited state intramolecular charge transfer processes in opening up new pathways for chemical change, energy transfer and decay in molecular systems. The second area is aimed at the key aspect of chemical reactions, namely the identification and study of the properties of the short-lived chemical intermediates occurring in chemical reactions.

Picosecond laser techniques were both used and developed to obtain new information on ultrafast molecular processes in liquids. From these studies, primarily of organic molecules, were have gained insight into: the physical and chemical pathways by which excited state molecules dissipate their energy by proton and electron transfer phenomena, the nature of intermolecular motions (cage effects in chemical reactions) and intramolecular motions about methylene groups, photodissociation of excited molecules and energy relaxation in the fragments generated, e.g. diphenylcarbene, the photoionization and subsequent electron solvation dynamics of pyrene in alcohols. The information we have obtained has important implications in the photostability of dye lasers and polymer systems, the development of new lasers based on the generation of large excited state populations in transient species; and the general effects of intense lasers on materials.

Photochromism is simply defined as the light induced reversible change of colour. The field has developed rapidly during the past decade as a result of attempts to improve the established materials and to discover new devices for applications.As photochromism bridges molecular, supramolecular and solid state chemistry, as well as organic, inorganic and physical chemistry, such a treatment requires a multidisciplinary approach and a broad presentation. The first edition (1990) provided an enormous amount of new concepts and data, such as the presentation of main families based on the pericyclic reaction mechanism, the review of new families, some bimolecular photocycloadditions and some promising systems. This new edition provides an efficient entry into this flourishing field, with the core content retained from the original work to provide a basic introduction into the different subjects. *Second edition of a work first published in 1990, now revised due to constant development of research. *Including updated lists of references (1989-2001), offering immediate access to recent developments.*Providing great basic interest and high application potential bringing scientists together from chemistry, physics and engineering.

Pulse Radiolysis presents an in-depth discussion of the pulse radiolysis technique, one of the most important and powerful means for detecting transient and relaxation phenomena and following their behavior in irradiated systems. The book covers the principle of pulse radiolysis, identifies various kinds of pulse radiolysis techniques, and discusses recent advancements in the field. The text also discusses new experimental pulse radiolysis techniques (basic and applied) in broad scientific fields such as physics, chemistry, biology, and engineering. These techniques include picosecond pulse radiolysis, single particle radiolysis, and muon-induced transient phenomena. Pulse Radiolysis provides essential information for all professionals involved with pulse radiolysis research.
