This book was released on 2000-10-09 with total page 337 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume comprises six chapters which explore the development and applications of the methods of computational chemistry. The first chapter is on new developments in coupled-cluster (CC) theory. The homotopy method is used to obtain complete sets of solutions of nonlinear CC equations. The correspondence between multiple solutions to the CCSD, CCSDT, and full CI equations is established, and the applications of the new approach in modeling molecular systems are discussed. The second chapter reviews the computational theory for the time-dependent calculations of a solution to the Schrödinger equation for two electrons and focuses on the development of propagators to the solution.The next chapter features a discussion on a new self-consistent field for molecular interactions (SCF-MI) scheme for modifying Roothaan equations in order to avoid basis set superposition errors (BSSE). This method is especially suitable for computations of intermolecular interactions. Details of the theory, along with examples of applications to nucleic acid base pair complexes, are given. This chapter is well complemented by the following chapter, which reports the current status of computational studies of aromatic stacking and hydrogen bonding interactions among nucleic acid bases. The next chapter reveals the possibility of calculating the kinetics of chemical reactions in biological systems from the first principles. The last chapter reviews the results of rigorous ab initio studies of the series of derivatives of methane, silane, and germane. The presented molecular and vibrational parameters complement experimental data for these systems. In addition, the theoretical approach allows the prediction of the effects of halogeno-substitutions on their structures and properties.

This book was released on 2001-08-22 with total page 277 pages. Available in PDF, EPUB and Kindle. Book excerpt: There are strong indications that, in the 21st century, computational chemistry will be a prime research tool not only for the basic sciences but also for the life and materials sciences. Recent developments in nanotechnology allow us to detect a layer of single atoms. Researchers are able not only to image but also to manipulate molecules and atoms. It does not take much imagination to realize that before performing such a task on a real system it is much easier and faster to study models on computers. That is the aim of this volume — it provides up-to-date reviews which cover representative areas of computational chemistry.In Chapter 1, Y Ishikawa and M J Vilkas provide a review of multireference Moller-Plesset (MR-MP) perturbation theory. Fifteen years ago Roberto Car of Princeton University and Michele Parrinello of Max Planck Institute introduced a method that revolutionized electronic structure calculations for molecules, liquids and solids. Ursula Rothlisberger, a former member of Parrinello's group, reviews the formation of the method in its most common implementations in Chapter 2. In the third chapter, Isaac B Bersuker describes the general theory of the combined quantum mechanics-molecular mechanics (QM/MM) approach. In Chapter 4, Marcel Allavena and David White present a review of applications of computational chemistry to proton transfer, the primary process for acid-base chemistry on zeolites. Chapter 5 is a review by S Roszak and J Leszczynski of recent data on the clusters formed from the charged ion and weakly interacting ligands. The last chapter, contributed by Carlos R Handy, is devoted to recent developments in the incorporation of continuous wavelet transform analysis into quantum operator theory.

Book excerpt: There have been important developments in the last decade: computers are faster and more powerful, code features are enhanced and more efficient, and larger molecules can be studied — not only in vacuum but also in a solvent or in crystal. Researchers are using new techniques to study larger systems and obtain more accurate results. This is impetus for the development of more efficient methods based on the first-principle multi-level simulations appropriate for complex species.Among the cutting-edge methods and studies reviewed in this decennial volume of the series are the Density Functional Theory (DFT) method, vibrational electron energy loss spectroscopy (EELS), computational models of the reaction rate theory, the nuclear magnetic resonance triplet wavefunction model (NMRTWM) and biological reactions that benefit from computational studies.

This book was released on 2002-07-30 with total page 261 pages. Available in PDF, EPUB and Kindle. Book excerpt: Vast progress in the area of computational chemistry has been achieved in the last decade of the 20th century. Theoretical methods such as quantum mechanics, molecular dynamics and statistical mechanics have been successfully used to characterize chemical systems and to design new materials, drugs and chemicals. With this in mind, the contributions to this volume were collected.The contributions include predictions of the transport properties of molecular structures at the atomic level, which is of importance in solving crucial technological problems such as electromigration or temperature and statistical effects.Although currently restricted to calculation of systems containing no more than a few thousand atoms, nonempirical (ab initio) quantum chemical methods are quickly gaining popularity among researchers investigating various aspects of biological systems. The development of efficient methods for application to large molecular systems is the focus of two chapters. They include an overview of development and applications of parallel and order-N Density Functional Theory (DFT) methods and the development of new methods for calculation of electron dynamical correlation for large molecular systems.For small and medium-sized molecules, chemical accuracy of quantum chemical predictions has already been achieved in many fields of application. Among the most accurate methods are Coupled Cluster (CC) approaches, but their accuracy comes at a price — such methodologies are among the most computationally demanding. Two chapters review approximate strategies developed to include triple excitations within the coupled cluster and the performance of the explicitly correlated CC method based on the so-called R12 ansatz.The Quantum Molecular Dynamics (QMD) approach has revolutionized electronic structure calculations for molecular reactions. The last chapter of the volume provides details of QMD studies on interconversion of nitronium ions and nitric acid in small water clusters.

This book was released on 2003-12-15 with total page 361 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 1999-11-05 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume presents a balanced blend of methodological and applied contributions. It supplements well the first three volumes of the series, revealing results of current research in computational chemistry. It also reviews the topographical features of several molecular scalar fields. A brief discussion of topographical concepts is followed by examples of their application to several branches of chemistry.The size of a basis set applied in a calculation determines the amount of computer resources necessary for a particular task. The details of a common strategy — the ab initio model potential method — which could be used to minimize such a task are revealed in the subsequent contribution. Such an approach is applied to atoms, molecules and solids. Two chapters are devoted to the prediction of solvent effects in biological systems. These effects are significant for interactions of nucleic acid bases and crucial for an evaluation of the free energies that govern the associations of macromolecules in aqueous solutions.A chapter on the developments and applications of the multireference Moller-Plesset method could be used as a reference in theoretical studies of systems where both the dynamical and nondynamical correlation effects should be accounted for. This technique is an efficient tool in such investigations. An explosive application of computational techniques — studies of detonation initiation and sensitivity in energetic compounds — is discussed in detail in the last chapter. The computational treatment of such unstable compounds allows the prediction of their crucial properties without being subject to their destructive forces.
