TheAdvances in Chemical Physics series provides the chemical physics field with a forum for critical, authoritative evaluations of advances in every area of the discipline. This volume explores the following topics:Thermodynamic Perturbation Theory for Associating MoleculesPath Integrals and Effective Potentials in the Study of Monatomic Fluids at EquilibriumSponteneous Symmetry Breaking in Matter Induced by Degeneracies and PseudogeneraciesMean-Field Electrostatics Beyond the Point-Charge DescriptionFirst Passage Processes in Cellular BiologyTheoretical Modeling of Vibrational Spectra and Proton Tunneling in Hydroen-Bonded Systems

STUART A. RICE, PhD,received his master's degree and doctorate from Harvard University and was a junior fellow at Harvard for two years before joining the faculty of The University of Chicago in 1957, where he is currently the Frank P. Hixon Distinguished Service Professor Emeritus.

AARON R. DINNER, PhD,received his bachelor's degree and doctorate from Harvard University, after which he conducted postdoctoral research at the University of Oxford and the University of California, Berkeley. He joined the faculty at The University of Chicago in 2003.
