Advances in Quantum Chemistry publishes articles and invited reviews by leading international researchers in quantum chemistry. Quantum chemistry deals particularly with the electronic structure of atoms, molecules, and crystalline matter and describes it in terms of electron wave patterns. It uses physical and chemical insight, sophisticated mathematics, and high-speed computers to solve the wave equations and achieve its results. Advances highlights these important, interdisciplinary developments. Volume 37 includes proceedings of the 1998 Korea-Japan DV-Xa Joint Symposium. Emphasis is placed on atomic spectroscopy and material science, including the computation of electronic states of materials.
