Book Description
Photochemistry — 7 is a collection of plenary lectures presented at the Seventh Symposium on Photochemistry held in Leuven, Belgium, on July 24-28, 1978. Contributors explore a wide range of topics relating to photochemistry, including the chemistry of exciplexes and the photo-oxidation of polymers. Excited state electron-transfer reactions of transition metal complexes are also discussed, along with the photochemistry of diazocompounds and azides in argon. This volume is comprised of 12 chapters and begins with a review of the role of exciplex intermediates in photocycloadditions involving polyenes and excited anthracenes. The reader is then introduced to the use of photochemical conversion of one molecule into another as an approach to the synthesis of natural products. The following chapters focus on the use of the Linear Combination of Fragment Configurations approach to generate qualitative potential energy surfaces; reciprocal interactions of polymers with excited solutes or polymer-bound chromophores; photochemistry of some three-membered heterocycles; cis-trans photoisomerization of 4-nitrostilbenes; and electron transfer in monolayer assemblies. This monograph will be of value to chemists.

Book Description
This volume emphasizes the involvement of all facets of biology in the analysis of environmentally controlled movement responses. This includes biophysics, biochemistry, molecular biology and as an integral part of any approach to a closer understanding, physiology. The initial euphoria about molecular biology as the final solution for any problem has dwindled and the field agrees now that only the combined efforts of all facets of biology will at some day answer the question posed more than hundred years ago: "How can plants see?". One conclusion can be drawn from the current knowledge as summarized in this volume. The answer will most likely not be the same for all systems.

Book Description
Molecular Photobiology: Inactivation and Recovery describes the deleterious photochemical reactions occurring in biological systems. This book is composed of 10 chapters that specifically tackle light interactions in the ultraviolet region of the spectrum resulting to damaged proteins and nucleic acids in living systems. This book deals first with the kinds of photochemical reactions that can occur and the possible effects of photochemistry on molecular, cellular, and organismal levels. The succeeding chapters highlight the principle of recovery mechanisms, wherein evidence shows that cells can repair their damaged genetic material, and thus recover from the otherwise inactivating effects of light. The remaining chapters are devoted to the comparison and contrast of some biological effects of ionizing radiation and those of ultraviolet radiation. This book is of value to molecular photobiologists, photochemists, biochemists, and radiation scientists and researchers.

Book Description
Providing a theoretical background for inorganic mass spectrometry, this text describes classical applications of four modern mass spectrometers - magnetic sector, quadrupole, time-of-flight, and ion trap - and illustrates how they have impacted elemental and isotopic analysis. The book features examples that concentrate on routine and non-routine applications of inorganic analysis techniques.

Book Description
This book provides detailed protocols for research in plant photomorphogenesis. The collection includes a broad range of topics including assays for shade avoidance responses, assays for light-dependent protein-protein interactions, photobody detection with immunofluorescence and the super-resolution imaging method, protein complex isolation from plants, detection of homodimer and monomer of photoreceptor UVR8 with immunoblotting analysis, assays for seedling greening, procedures for studying skotomorphogenesis, phenotypic study of photomorphogenesis at the seedling stage, expression of Cryptochrome in insect cells, and more. Written for the highly successful Methods in Molecular Biology series, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls. Authoritative and practical, Plant Photomorphogenesis: Methods and Protocols serves as an ideal guide for researchers and students who are new to the field, as well as a stepping stone for experienced researchers to further their skills in this fast-developing field.

Book Description
Induction of DNA damage by sunlight is a major deleterious event in living organisms. Recent developments have dramatically improved our understanding of the photochemical processes involved at the sub-picosecond time scale and along with next generation sequencing and data processing has generated a need for a complete up-to-date coverage of the field. Written in an accessible and comprehensive manner, DNA Photodamage will appeal to all scientists working in the area whether specialists in the discipline or not and provides a complete coverage of the field, from ultrafast spectroscopy to biomedical research. Bridging the gap between photophysical and photochemical research on model systems, and in vivo and in vitro biological studies, this book aims to identify the most important research trends in the field and review their major findings.

Book Description
Concern is often expressed that our environment may include an increasingly large variety of mutagens, but the extent of the potential hazard they pose has yet to be fully evaluated. A variety of empirical procedures has been devised with which to estimate the mutagenic potency of suspect agents, and the relative merits of different tests are currently under debate. Although such tests are of great value, and are indeed indispensable, they are not, nevertheless, sufficient. In the long term, accurate estimation of hazard will also require a better understanding of the various mechanisms of mutagenesis, and in many instances these remain remarkably elusive. Our knowledge and appreciation of the problem has increased substantially over the last few years, but the precise way in which many mutagens cause mutations is not yet known. The aims of this conference were therefore two-fold. The first was to survey present information about mutagenic mechanisms, drawing together data from work with various experimental approaches and organisms, in order to discern the principles governing the action of different mutagens. The second was to examine the implications of such principles for the execution and evaluation of test procedures, and critically assess the research areas that need further attention in order to improve the interpretation of test results.

Book Description
Photochemical Processes in Polymer Chemistry-2 contains invited lectures presented at the Second IUPAC Symposium on Photochemical Processes in Polymer Chemistry held at Leuven, Belgium on June 2-4, 1976. This book contains 11 papers separated as chapters. Topics include energy transfer processes; photoinitiation of polymerization; solid-state polymerization mechanisms; photoinduced ionic polymerizations; and photoconductive polymers. This text also discusses energy transfer phenomena in high polymer systems; laser spectroscopical methods for the study of primary processes during the photodegradation; photooxidation of high polymers; and reaction selectivity and molecular association in photochemical reactions of nucleic acids and their constituents. New developments in photochromic polymers and related phenomena, as well as the design of photoreactive polymer systems for imaging processes are also explained.
