Computational Chemistry

Author: Errol G. Lewars
Publisher: Springer
ISBN: 9783319309163
Release Date: 2016-09-20
Genre: Science

This is the third edition of the successful text-reference book that covers computational chemistry. It features changes to the presentation of key concepts and includes revised and new material with several expanded exercises at various levels such as 'harder questions' for those ready to be tested in greater depth - this aspect is absent from other textbooks in the field. Although introductory and assuming no prior knowledge of computational chemistry, it covers the essential aspects of the subject. There are several introductory textbooks on computational chemistry; this one is (as in its previous editions) a unique textbook in the field with copious exercises (and questions) and solutions with discussions. Noteworthy is the fact that it is the only book at the introductory level that shows in detail yet clearly how matrices are used in one important aspect of computational chemistry. It also serves as an essential guide for researchers, and as a reference book. div“/div>

Numerische Simulation in der Molek ldynamik

Author: Michael Griebel
Publisher: Springer-Verlag
ISBN: 9783642187797
Release Date: 2013-03-07
Genre: Mathematics

Das Buch behandelt Methoden des wissenschaftlichen Rechnens in der Moleküldynamik, einem Bereich, der in vielen Anwendungen der Chemie, der Biowissenschaften, der Materialwissenschaften, insbesondere der Nanotechnologie, sowie der Astrophysik eine wichtige Rolle spielt. Es führt in die wichtigsten Simulationstechniken zur numerischen Behandlung der Newtonschen Bewegungsgleichungen ein. Der Schwerpunkt liegt hierbei auf der schnellen Auswertung kurz- und langreichweitiger Kräfte mittels Linked Cell-, P$/\3$M-, Baum- und Multipol-Verfahren, sowie deren paralleler Implementierung und Lastbalancierung auf Rechensystemen mit verteiltem Speicher. Die einzelnen Kapitel beinhalten darüberhinaus detailierte Hinweise, um die Verfahren Schritt für Schritt in ein Programmpaket umzusetzen. In zahlreichen farbigen Abbildungen werden Simulationsergebnisse für eine Reihe von Anwendungen präsentiert.

Lehrbuch der Mathematischen Physik

Author: Walter Thirring
Publisher: Springer-Verlag
ISBN: 9783709166468
Release Date: 2013-03-07
Genre: Science

In der Quantentheorie werden Observable durch Operatoren im Hilbert-Raum dargestellt. Der dafür geeignete mathematische Rahmen sind die Cx - Algebren, welche Matrizen und komplexe Funktionen verallgemeinern. Allerdings benötigt man in der Physik auch unbeschränkte Operatoren, deren Problematik eigens untersucht werden muß. Dementsprechend werden zunächst mathematische Fragen studiert und dann die Methoden auf atomare Systeme angewandt. Obgleich man außer dem Wasserstoffatom kaum explizit lösbare Probleme findet, lassen sich nicht nur allgemeine qualitative Fragen, etwa bezüglich des Energiespektrums und Streuverhaltens, beantworten, sondern auch quantitativ kann man auch für kompliziertere Systeme für meßbare Größen Schranken teils befriedigender Genauigkeit finden. Inhaltsverzeichnis: Einleitung: Die Struktur der Quantentheorie; Größenordnungen atomarer Systeme.- Die mathematische Formulierung der Quantenmechanik: Lineare Räume; Algebren; Darstellungen im Hilbertraum; Einparametrige Gruppen; Unbeschränkte Operatoren und quadratische Formen.- Quantendynamik: Das Weyl-System; Der Drehimpuls; Die Zeitentwicklung; Der Limes t ; Störungstheorie; Stationäre Streutheorie.- Atomare Systeme: Das Wasserstoffatom; Das H-Atom in äußeren Feldern; Heliumartige Atome; Streuung am einfachen Atom; Komplexe Atome; Kernbewegung und einfache Moleküle.

Theory and Application of Quantum Molecular Dynamics

Author: John Z. H. Zhang
Publisher: World Scientific
ISBN: 9810233884
Release Date: 1999
Genre: Science

This book gives an updated and detailed presentation of modern quantum-mechanical treatments and practical computational methods for dynamical processes of small molecular systems. The main emphasis is on the recent development of successful theories and computational methods for the reactive scattering process. Specific applications are given in detail for a number of benchmark chemical reaction systems in the gas phase and gas surface. Differing from traditional physics books focusing on abstract collision theory for elastic collisions, the book has been written in a fashion in which the development of general reactive or rearrangement scattering theory is accompanied by practical applications for realistic reaction systems.

Release Date: 2012-10-11
Genre: Science

This book consists of over 300 problems (and their solutions) in structural inorganic chemistry at the senior undergraduate and beginning graduate level. The topics covered comprise Atomic and Molecular Electronic States, Atomic Orbitals, Hybrid Orbitals, Molecular Symmetry, Molecular Geometry and Bonding, Crystal Field Theory, Molecular Orbital Theory, Vibrational Spectroscopy, and Crystal Structure. The central theme running through these topics is symmetry, molecular or crystalline. The problems collected in this volume originate in examination papers and take-home assignments that have been part of the teaching of the book's two senior authors' at The Chinese University of Hong Kong over the past four decades. The authors' courses include Chemical Bonding, Elementary Quantum Chemistry, Advanced Inorganic Chemistry, X-Ray Crystallography, etc. The problems have been tested by generations of students taking these courses.
