This note deals with the basics of
quantum chemistry, beginning with introductory theory and methods. It covers the
Schrödinger equation, the Hartree-Fock approach, the use of basis sets and
pseudopotentials. This, along with more advanced topics such as Density
Functional Theory (DFT), multiconfigurational self-consistent field (MCSCF)
methods, as well as techniques for performing calculations for excited states,
introduces solvation models, and global optimization methods, among other
things, and discusses in some detail the GAMESS package in computational
chemistry. The book provides a good framework for beginners, while advanced
students can find appropriate theoretical backbones to support their practical
quantum chemical research.
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.
