背景

Molecular Modelling. Semi-Empirical and Empirical Methods of Theoretical Chemistry,The basic equations of the semi-empirical methods of quantum chemistry are developed and the most commonly used approximations are given and their utility in solving chemical problems is dicussed. The principles of molecular mechanics are presented with a special emphasis on the molecular force field and on the possible chemical applications.
