Publisher: World Scientific Publishing Company Number Of Pages: 344 Publication Date: 2006-06-01 ISBN-10 / ASIN: 9812567429 ISBN-13 / EAN: 9789812567420 Binding: Paperback
The gap between experimental objects and models for calculations in chemistry is being bridged. The size of experimental nano-objects is decreasing, while reliable calculations are feasible for larger and larger molecular systems. The results of these calculations for isolated molecules are becoming more relevant for experiments. However, there are still significant challenges for computational methods. This series of books presents reviews of current advances in computational methodologies and applications.
Chapter 1 of this volume provides an overview of the theoretical and numerical aspects in the development of the polarizable continuum model (PCM). Chapter 2 demonstrates a multiplicative scheme used to estimate the properties of two- and three-dimensional clusters from the properties of their one-dimensional components. Chapter 3 discusses the application of ab initio methods for a reliable evaluation of the characteristics of hydrogen-bonded and van der Waals complexes.
Ab initio quantum-chemical methods are popular among researchers investigating various aspects of DNA. The properties of DNA base polyads linked by base–base hydrogen bonds are reviewed in Chapter 4, while Chapter 5 reviews the primary radiation-induced defects in nucleic acid building blocks, and how DNA can be influenced by chemical and environmental effects. Finally, Chapter 6 discusses available experimental data of DNA bases, base pairs, and their complexes with water.
Summary: good summary of trends Rating: 4
Stay current in computational chemistry with this text. The chapters summarise recent techniques and show the continuing influence of advances in computer hardware and software. Basically, the molecules that you can usefully simulate keep getting bigger.
Several chapters discuss ab initio methods. Conceptually, these are always attractive, in enabling a first principles construction of molecules or reactions. There is extensive specific discussion of applying the methods towards DNA molecules. In part to predict various three dimensional structures.
The book is ideal for a graduate student in the field.
