The book presents the quantum theory of the electronic structure of atoms and focuses on the electronic structures and reactivity of atoms and molecules. It shows how to draw molecules such as the oxygen and water to far more complex molecules, using molecular orbital theory, and hybridization of orbitals. It gives quite clear picture of molecular polarity, together with symmetrical and unsymmetrical distribution of an atom or molecule when developing a temporary (instantaneous) dipole. The book provides a clear and comprehensive summary of oxidative and reductive processes. Electronegativity on oxidation and reduction is also introduced. Examples are provided. It enables the reader to master the principles and applications of organic functional groups. Readers will find information quickly and easily about alkanes, alkenes, alkynes and arenes. Bonding with p and s is also introduced. It explains the fundamental principles of nomenclature methods, using IUPAC (International Union of Pure and Applied Chemistry) and enables the reader to apply it accurately and with confidence. The book is replete with examples for guidance and there are extensive and complicated figures to direct the reader to nomenclature quickly. It gives hands-on chemistry activities with real-life functions. It provides clear and thorough understanding of carbohydrates, polysaccharides, starch and glycogen, cellulose and chitin, nucleotide, nitrogenous hydroxyl and phosphate, lipids, protein, ester, lipoprotein, glycolipid, steroid, mucin, etc. it is a useful reference for health professionals, practicing physicists, chemists, and materials scientists.

Quantum Monte Carlo is a large class of computer algorithms that simulate quantum systems to solve many body systems in order to investigate the electronic structure of many-body systems. This book presents a numeric approach to determine the electronic structure of atoms, molecules and solids. Because of the simplicity of its theoretical concept, the authors focus on the variational Quantum-Monte-Carlo (VQMC) scheme. The reader is enabled to proceed from simple examples as the hydrogen atom to advanced ones as the Lithium solid. Several intermediate steps cover the Hydrogen molecule, how to deal with a two electron systems, going over to three electrons, and expanding to an arbitrary number of electrons to finally treat the three-dimensional periodic array of Lithium atoms in a crystal. The exmples in the field of VQMC are followed by the subject of diffusion Monte-Calro (DMC) which covers a common example, the harmonic ascillator. The book is unique as it provides both theory and numerical programs. It includes rather practical advices to do what is usually described in a theoretical textbook, and presents in more detail the physical understanding of what the manual of a code usually promises as result. Detailed derivations can be found at the appendix, and the references are chosen with respect to their use for specifying details or getting an deeper understanding . The authors address an introductory readership in condensed matter physics, computational phyiscs, chemistry and materials science. As the text is intended to open the reader's view towards various possibilities of choices of computing schemes connected with the method of QMC, it might also become a welcome literature for researchers who would like to know more about QMC methods. The book is accompanied with a collection of programs, routines, and data. To download the codes, please follow http://www.wiley-vch.de/books/sample/3527408517_codes.tar.gz

That there have been remarkable advances in the field of molecular electronic structure during the last decade is clear not only to those working in the field but also to anyone else who has used quantum chemical results to guide their own investiga tions. The progress in calculating the electronic structures of molecules has occurred through the truly ingenious theoretical and methodological developments that have made computationally tractable the underlying physics of electron distributions around a collection of nuclei. At the same time there has been consider able benefit from the great advances in computer technology. The growing sophistication, declining costs and increasing accessibi lity of computers have let theorists apply their methods to prob lems in virtually all areas of molecular science. Consequently, each year witnesses calculations on larger molecules than in the year before and calculations with greater accuracy and more com plete information on molecular properties. We can surely anticipate continued methodological develop ments of real consequence, and we can also see that the advance in computational capability is not about to slow down. The recent introduction of array processors, mUltiple processors and vector machines has yielded a tremendous acceleration of many types of computation, including operations typically performed in quantum chemical studies. Utilizing such new computing power to the ut most has required some new ideas and some reformulations of existing methods.
