Document from the year 2016 in the subject Chemistry - Physical and Theoretical Chemistry, University of Duisburg-Essen, language: English, abstract: This is a book for all chemists who don't want to become theoretical chemists, but who want to understand user articles and presentations with theoretical concepts included and who want to use theoretical chemistry for there own projects. It gives an overview about: Hartree Fock Theory, Post-Hartree-Fock-Methods, Density-Functional-Theory, Solid-State-Physics, Force-Field Methods and Molecular Dynamics. Everything the chemist of the 21th century should know about Theoretical Chemistry, to be able to read articles with a satisfying yield of new informations, to be able to effectively talk to and work with theoretical chemists and to plan own calculations. The author offers an overview about Post-Hartree-Fock-Methods (Coupled Cluster (incl. Example for Application of Perturbation-Theory), Full CI, explicitly correlated methods) Density-Functional-Theory (Basic Equations, reason of lower computational cost, important Types of Functionals (LSD-Functionals, GGA-Functionals, Hybrid-Functionals)), Important points in searching the right method), Force-Field-methods (Basic Theory, Basic Equations, practical tips as tool in quantum-chemical Calculations), theoretical Solid-State Physics (differences to quantum chemical equations, special behavior of solid-state-systems, atomic groups with single-particle-behavior - like phonons, polarons, ...), the role of special techniques (Perturbation Theory, Group Theory) and shows connections of those techniques to molecular dynamics. For that he shows all necessary mathematics and derivations, when they are needed but just as deep as necessary. Not with the target to make the reader a theoretician. In front of the derivative part he commits his pictorial imagination of Hilbert-space, basis set, and quantum-chemical-calculations.
