# Description

The description of quantum systems is fundamental to an understanding of many problems in chemistry and physics. This volume records a representative slection of the papers delivered at the second European Workshop on

**Quantum Systems in Chemistry and Physics**which was held at Jesus College, Oxford, April 6-9, 1997. The purpose of this international Workshop was to bring together chemists and physicists with a common interest--the quantum mechanical many-body problem--and to encourage collaboration and exchange of ideas on the fundamentals by promoting innovative theory and conceptual development rather than improvements in computatorial techniques and routine applications.- Covers the following topics:
- Density matrices and density functional theory
- Electron correlation
- Relativistic effects
- Valence theory
- Nuclear motion
- Response theory
- Condensed matter
- Chemical reactions
