Comparison of ab initio quantum chemistry with experiment for small molecules : the state of the art by Rodney J Bartlett( Book )

14 editions published in 1985 in English and held by 297 WorldCat member libraries worldwide

At the American Chemical Society meeting in Philadelphia, Pennsylvania, U.S.A., a symposium was organized entitled, "Comparison of Ab Initio Quantum Chemistry with Experiment: State-of-the-Art." The intent of the symposium was to bring together forefront experimen­ talists, who perform the types of clean, penetrating experiments that are amenable to thorough theoretical analysis, with inventive theore­ ticians who have developed high accuracy ab initio methods that are capable of competing favorably with experiment, to assess the current applicability of theoretical methods in chemistry. Contributions from many of those speakers (see Appendix A) plus others selected for their expertise in the subject are contained in this volume. Such a book is especially timely, since with the recent develop­ ment of new, more accurate and powerful ab initio methods coupled with the exceptional progress achieved in computational equipment, ab initio quantum chemistry is now often able to offer a third voice to resolve experimental discrepancies, assist essentially in the interpre­ tation of experiments, and frequently, provide quantitatively accurate results for molecular properties that are not available from experiment
Many-body methods in chemistry and physics : MBPT and coupled-cluster theory by Isaiah Shavitt( Book )

20 editions published between 2009 and 2010 in English and held by 264 WorldCat member libraries worldwide

Describes the mathematical and diagrammatic techniques employed in the popular many-body methods to determine molecular structure, properties and interactions.--Résumé de l'éditeur
Correlation and localization( Book )

7 editions published in 1999 in English and held by 177 WorldCat member libraries worldwide

This volume contains review and research articles in a field of quantum chemical methodology: the theory of electron correlation and the localization problem. Correlation energy (i.e., the energy beyond the Hartree-Fock) plays an important role in the theoretical description of several chemical processes (reactions, excitations, ionization) while localization in quantum chemistry usually emerges as a mathematical transformation of the wave function. The connection between these two issues is provided by the need to evaluate correlation energy for larger molecules, which is much easier in terms of localized contributions. The articles selected discuss copuled cluster, perturbational and geminal-based schemes, and cover wave function as well as density based approaches
Recent advances in coupled-cluster methods by Rodney J Bartlett( Book )

13 editions published in 1997 in English and Undetermined and held by 144 WorldCat member libraries worldwide

Today, coupled-cluster (CC) theory has emerged as the most accurate, widely applicable approach for the correlation problem in molecules. Furthermore, the correct scaling of the energy and wavefunction with size (i.e. extensivity) recommends it for studies of polymers and crystals as well as molecules. CC methods have also paid dividends for nuclei, and for certain strongly correlated systems of interest in field theory. In order for CC methods to have achieved this distinction, it has been necessary to formulate new, theoretical approaches for the treatment of a variety of essential quantities

Molecular Interactions and Properties with Many-Body Methods by Rodney J Bartlett( )

5 editions published between 1990 and 1996 in English and held by 4 WorldCat member libraries worldwide

During the course of this research, CC/MBPT theories have been established as being among the most accurate available, and very efficient and generally applicable computer codes have been developed to perform CC/MBPT calculations. These methods have been employed for the first time in large scale ab initio calculations of potential energy surfaces. Two of the papers produced in this research have been identified by authorities as being among the most influential papers in the 50-year history of computational quantum chemistry, and four have been identified by Current Contents as qualifying as science citation classics.

Molecular Interactions with Many-Body Methods by Rodney J Bartlett( Book )

4 editions published between 1982 and 1988 in English and held by 4 WorldCat member libraries worldwide

This report summarized publications and invited presentations supported by our AFOSR grant on 'Molecular Interactions with Many-Body Methods'. In this effort new many-body methods have been developed to treat open-shell molecules; to apply to properties like moments, polarizabilities, hyperpolarizabilities, spin-densities and spin-spin coupling constants; infra-red spectra; and a variety of applications to interesting molecules including the unknown metastable N3H3 system. The latter molecule, though isoelectronic with ozone and cyclopropane is not known experimentally. However, we find that it should exist in three stable structures. Furthermore, we have pre-edited its IR spectra to aid in its experimental identification, which should be possible in matrix isolation. Other applications work has focused on the accurate, numerical orbital treatment of anions. (mjm)

Computational Prediction of Kinetic Rate Constants( )

3 editions published between 2006 and 2009 in English and held by 3 WorldCat member libraries worldwide

This is the Final Technical Report / Final Phase I Summary Report for the STTR on topic #AF05-T010 entitled Computational Prediction of Kinetic Rate Constants. In Phase I it has been shown that the combination of electronic structure offered by the ACES program system and the user-friendly interface of HyperChem can be combined together to provide the data required from quantum chemistry to provide thermal rate constants for molecules. The actual rate constant evaluation is accomplished in the new module, ACESRATE, using transition state theory, variational transition state theory, and RRKM. All of these methods were coded into ACESRATE in Phase I. The primary objective of the project was the design and testing of the interface that makes such calculations easy for non-expert users

Coupled Cluster and Electron Correlation Workshop (1997) "Fifty Years of the Correlation Problem" Held in Cedar Key, Florida on June 15-19, 1997( Book )

2 editions published in 1997 in English and held by 2 WorldCat member libraries worldwide

The Coupled Cluster Theory Electron Correlation Workshop 'Fifty Years of the Correlation Problem' was held at Cedar Key, Florida, from June 15-19, 1997, to recognize the essential developments for one of the dominant topics in the quantum theory of atoms, molecules, and solids. The instantaneous Coloumbic interactions among electrons that correlate their motion (the electron correlation problem) has been the focal point of ab initio quantum chemistry and physics for many years. Only with the proper inclusion of electron correlation in approximate solutions of the Schroedinger (or Dirac-Fock) equation is it possible to provide predictive accuracy for most properties of atoms and molecules. Such quantities include energetics (involving multiplets, dissociation pathways, and activation barriers), excited states and first- and second-order properties (like moments, field, gradients, polarizabilitles, and magnetic susceptibilities), and vibrational, electronic, EPR and NMR spectra, among others
Molecular Interactions with Many-Body Perturbation Theory( Book )

2 editions published between 1980 and 1981 in English and held by 2 WorldCat member libraries worldwide

Very efficient computer codes to perform many-body perturbation theory (MBPT) and coupled cluster method (CCM) calculations have been written and employed for the first time in large-scale ab initio calculations of potential energy surfaces. (Author)
Metastability in Molecules( )

2 editions published between 1993 and 1994 in English and held by 2 WorldCat member libraries worldwide

Synthesis and detonation of energetic materials involves several critical oxidation processes and associated intermediates. Carbonyl oxide, and its cyclic isomeric form, dioxirane, are two key compounds in such processes. Carbonyl oxide has never been observed experimentally, though it is one of the most discussed compounds awaiting detection. We performed high level coupled- cluster CCSD(T) calculations to characterize carbonyl oxide. These studies employed recently developed open-shell analytical gradients methods for CCSD(T), without which structures and vibrational frequencies would be difficult to obtain. The Delta H sub f deg (298) for carbonyl oxide is found to be 30.2 kcal/ mol, while the barrier to isomerization to dioxirane is 19.2 kcal/mol. CCSD(T) vibrational frequencies of both species are presented to facilitate identification along with the 18 O isotope shifts. Shifts as high as 45 /cm permit experimental discrimination between the two forms. Carbonyl oxide is found to be far more zwitterionic than lower level theoretical studies would suggest, in line with the viewpoint of synthetic chemists
