Physico-chemical Properties of Nucleic Acids, Volume I deals with the intrinsic properties of nucleic acids (macromolecules) and their components. This volume includes the analysis of different types of bindings or interactions mechanisms such as photodynamic and radiation effects and fluorescence. Nine chapters comprise this volume. A number of chapters in the beginning of this book emphasize purines and pyrimidines. Dipole moments and charge transfer interactions are some of the specific topics covered regarding purines and pyrimidines. The topic of nucleic acids and components is discussed in detail in the middle up to the last part of the book, wherein electrical properties and energy transfer are explored. Other aspects covered include developments in fluorescence; free radicals in aqueous solutions; and irradiated single crystals. This volume will cater to undergraduates and graduate students as well as to researchers in the major fields of biology, chemistry, and physics.
