Opis

Comprehensive theoretical and experimental analysis of UV-radiation and low energy electron induced phenomena in nucleic acid bases (NABs) and base assemblies are presented in this book. NABs are highly photostable; the absorbed energy is dissipated in the form of ultrafast nonradiative decay. This book highlights the possible mechanisms of these phenomena which is important for all living species and discusses technical challenges in exploration of these processes. This volume will be of particular interest for those involved in understanding the photophysical/photochemical properties of nucleic acids. All chapters are written by the world's leading experts, both from the experimental and computational areas.

Recenzje

From the reviews:

"The editors ... succeed in creating a balanced portrait of their interdependent efforts in the book's 21 chapters. ... the book contains a number of excellent individual reviews that will benefit workers interested in excited states in small DNA model systems and in the mechanisms by which low-energy electrons induce strand breaks. There are excellent references to the recent and older literature throughout the book that will be valued by established and new workers in the field." (Bern Kohler, Journal of the American Chemical Society, Vol. 131 (6), 2008)

This volume presents a comprehensive overview of theoretical and experimental data on Ultraviolet radiation and low energy electron induced phenomena in nucleic acid fragments. The elucidation of possible mechanisms of these events is important for all living species and hence the technical challenges involved in the exploration of these processes are discussed. This volume will be of particular interest for those involved in understanding the photophysical and photochemical properties of nucleic acid bases, base assemblies, and also model systems related to nucleic acids. The chapter contributions assembled in Radiation Induced Molecular Phenomena in Nucleic Acids are written by theoreticians and experimentalists of international distinction.

Radiation Induced Molecular Phenomena in Nucleic Acids will be a useful reference to advanced undergraduates, postgraduates, academics, and researchers in computational chemistry and physics, physical chemistry, biochemistry, photochemistry, biophysics, molecular biology, materials science, and those engaged in nucleic acid research.
