This volume examines the requirements for a well-balanced description of energetically low-lying potential energy surfaces and the phenomena that occur on them. The theoretical aspects of the volume differ from traditional theoretical symposia by focusing on multiple surfaces and regions of potential energy surfaces away from stationary points. It examines the theory and application of multi-reference and multiple surface techniques. Critical comparisons of state of the art calculations with relevant experiments are included.

Edited by Mark R. Hoffmann, University of North Dakota, and Kenneth G. Dyall
