This volume provides a concise introduction to quantum chemistry and shows why the electronic behavior of atoms, molecules, and their chemical bonding can only be understood by way of quantum chemistry. It includes extensive discussions of applications such as spectroscopic methods of characterizing substances and computer-based techniques for modeling chemical molecules.

Second edition: new material on orbital models and spherical atoms.
