A Brief Review of Elementary Quantum Chemistry (PDF 50p)
This note covers the following topics: Motivation for Quantum
Mechanics, The Schrodinger Equation, Postulates of Quantum Mechanics, Some
Analytically Soluble Problems, Approximate Methods, Molecular Quantum Mechanics,
Solving the Electronic Eigenvalue Problem.
This note
presents advanced methods in quantum chemistry. Large systems are of particular
interest and serve to focus on Hartree-Fock theory and Density Functional Theory
with a notable selection of practical techniques for integral evaluation and
matrix construction. The Coulomb and exchange matrices are constructed, density
matrices purify, and large data sets necessary for quantum chemistry
calculations are stored and manipulated. The book gives insight into the
problems of large quantum chemistry calculations and presents the computational
techniques developed to overcome these problems, making it a most valuable aid
to researchers concerned with large molecular systems or with computational
chemistry.
The
book deals with the topics that are fundamentally related to the
theoretical foundations as well as innovative quantum chemistry
applications in molecular research. It caters to advanced topics, such
as numerical solution of ordinary differential equations with spectral
methods, use of pseudopotentials in composite methods, and quantum
chemical calculations for various chemical systems, including
exploration of molecular mechanisms involved in DNA mutations, charge
carrier mobility in organic electronics, and compounds of high energy
density. This book is designed for researchers and students who seek the
application of quantum chemistry to advanced topics in materials
science, biochemistry, and molecular engineering.
