Taschenbuch. Zustand: Neu. Neuware - Reactive PublishingComputational chemistry allows researchers, students, and technical professionals to explore molecular structure, bonding, energy, and reactivity through mathematical models and programmable workflows. Computational Chemistry with Python provides a practical introduction to the core ideas behind molecular modeling while showing how Python can be used to support calculations, visualization, and conceptual understanding.This book introduces molecular orbitals, quantum chemistry foundations, Hartree-Fock theory, density functional theory concepts, geometry optimization, and molecular energy calculations in a clear, applied format. Rather than treating computational chemistry as a purely theoretical subject, it connects the underlying mathematics and physical chemistry to practical coding workflows that help readers understand how molecules can be represented, approximated, and analyzed.Inside, readers will explore how computational models describe electrons, orbitals, molecular geometry, basis sets, energy surfaces, and approximation methods. The book also explains where common methods are useful, where they are limited, and how Python-based workflows can help make abstract chemical concepts more concrete.Designed for students, self-learners, chemists, data scientists, and technically minded readers, this guide offers a structured entry point into computational chemistry without assuming advanced prior experience in quantum mechanics.Topics include: Molecular structure and coordinate representationMolecular orbitals and electronic structure conceptsQuantum chemistry foundations for applied modelingHartree-Fock theory and self-consistent field ideasDensity functional theory concepts and practical interpretationGeometry optimization and potential energy surfacesMolecular energy calculations and result interpretationPython-based approaches for chemical computation and analysisComputational Chemistry with Python is for readers who want to understand how modern molecular modeling works and how Python can be used as a practical tool for learning, experimentation, and applied chemical analysis.…

Taschenbuch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - Recent years have seen the proliferation of new computer designs that employ parallel processing in one form or another in order to achieve maximum performance. Although the idea of improving the performance of computing machines by carrying out parts of the computation concurrently is not new (indeed, the concept was known to Babbage ), such machines have, until fairly recently, been confined to a few specialist research laboratories. Nowadays, parallel computers are commercially available and they are finding a wide range of applications in chemical calculations. The purpose of this volume is to review the impact that the advent of concurrent computation is already having, and is likely to have in the future, on chemical calculations. Although the potential of concurrent computation is still far from its full realization, it is already clear that it may turn out to be second in importance only to the introduction of the electronic digital computer itself.…

Taschenbuch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - Thisvolume isdevotedtomethodsfor thestudyoftheeffectsofrelativity on theelectronicstructure ofatomsand molecules. The accurate descrip tionofrelativisticeffectsinheavyatomshaslongbeenrecognizedasoneof the central problems ofatomic physics. Contemporary relativistic atomic structure calculations can be performed almost routinely. Recent years have seen agrowinginterestin thestudyoftheeffects ofrelativityon the structureofmolecules. Even for molecularsystemscontainingatoms from thesecondrowoftheperiodictable theenergyassociatedwith relativistic effects is often larger than that arising from electron correlation. For moleculescontainingheavieratoms relativistic effects become increasingly important,andforsystemscontainingveryheavyatomsrelativityisknown todominatemanychemicalproperties. In this volum~, one of the pioneers of relativistic atomic structure calculations,Ian P. Grant,providesadetailedsurveyofthecomputational techniquesemployedincontemporarystudiesoftheeffectsofrelativityon atomicstructure. Thisisanareaofresearchinwhichcalculationscanoften lead to a particularly impressive degreeofagreement between theoryand experiment. Furthermore, theseatomicstudies haveprovided manyofthe foundations of a fully relativistic quantum chemistry. However, the spherical symmetry ofatoms allows significantsimplificationsto bemade in their quantum mechanical treatment, simplifications which are not possibleinstudiesofmolecules. Inparticular, as is wellknown from non relativistictheoriesofmolecularelectronicstructure,itisalmostobligatory to invoke the algebraic approximation in molecular work and use finite basis set expansions. The problem of describing relativistic effects in molecules is addressed in Chapter2 by Stephen Wilson. This chapter is devotedtoab initiorelativisticmolecularstructurecalculationsinwhichall electrons are explicitly considered. The problem of induding relativistic effects in molecular studies is also addressed in Chapters3 and 4. In Chapter 3, Odd Gropen describes the use of relativistic effective core ix x Preface potentials in calculations on molecular systems involving heavy atoms. This approach can lead to more tractable algorithms than the methods described in Chapter2 and thus significantly extends the range of applications. The use of semiempirical methods has yielded a wealth of informationabouttheinfluenceofrelativityonthechemistryoftheheavier elements. Thisimportantarea is reviewed inChapter4 by Pekka Pyykk6.

Taschenbuch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - The papers collected in this volume were presented at an international symposium on Computational Methods in Chemistry. This symposium was sponsored by IBM Germany and was held September 17-19, 1979, in Bad Neuenahr, West Germany. According to Graham Richards [Nature 278, 507 (1979)] the 'Third Age of Quantum Chemistry' has started-;-where the results of quantum chemical calculations have become so accurate and reliable that they can guide the experimentalists in their search for the unknown. The particular example highlighted by Richards was the suc cessful prediction and subsequent identification of the relative energies, transition probabilities and geometries of the lowest triplet states of acetylene. The theoretical predictions were based chiefly upon the work of three groups: Kammer [Chern. Phys. Lett. ~, 529 (1970)] had made qualitatively correct predictions; Demoulin [Chern. Phys. 11, 329 (1975)] had calculated the potential energy curves for the two lowest triplet states (3 and 3 ) of B A acetylene; and Wetmore and Schaefer III [J. Chern. Phys. ~~ 1648 (1978)] had determined the geometries of the cis (3B and ~A ) and the trans (3B and 3A ) isomers of these two sta~es. Inua 2 2 guided search, Wendt, Hunziker and Hippler [J. Chern. PHys. 70, 4044 (1979)] succeeded in finding the predicted near infrared absorption of the cis triplet acetylene (no corresponding absorp tion for the trans form was found, which is in agreement with theory), and the resolved structure of the spectrum confirmed the predicted geometries conclusively. …
