The present volume gathers a series of selected and updated
contributions presented at the International Symposium on Applied
Theoretical Chemistry held in Havana, Cuba, July 2-6, 1990. This
Symposium was intended to illustrate current applications of Theoretical
Chemistry in different fields of Physical Chemistry. Theoretical
Chemistry has become a powerful tool of investigation in all areas of
Chemistry, Biochemistry, and Physical Chemistry. The plenary lectures
given in the Symposium were classified into four topics: Atom-Surface
Interactions, Chemical Reaction Mechanisms, Molecular Structure and
Properties, and Molecular Spectroscopy. We retain the same division in
this volume. Over 60 scientists from Cuba, Finland, France, Germany,
Great-Britain, Hungary, Italy, Spain, Sweden, USA, USSR, and Venezuela
participated in the Conference. Twenty plenary lectures were given by
distinguished members of the international scientific community.
Furthermore, a large number of posters were presented by younger experts
in various fields of Theoretical Chemistry. This International Symposium
was organized by the Faculty of Chemistry of the University of Havana
and the Cuban Chemical Society. It was an opportunity to bring together
in Havana several outstanding scientists from various countries of the
world. Havana is worldwide renown for its wonderful climate, the
hospitality of its inhabitants, and the proximity of beautiful touring
resorts.
