Highlighting the molecule-environment interactions that strongly influence spectra in condensed phases, Condensed-Phase Molecular Spectroscopy and Photophysics provides a comprehensive treatment of radiation-matter interactions for molecules in condensed phases as well as metallic and semiconductor nanostructures. Each chapter in this graduate-level molecular spectroscopy text contains problems ranging from simple through to complex. Topics unique to this text include the spectroscopy and photophysics of molecular aggregates and molecular solids, metals and semiconductors, and an emphasis on nanoscale size regimes.

ANNE MYERS KELLEY earned a BS in chemistry from the University of California, Riverside, in 1980 and a PhD in biophysical chemistry from the University of California, Berkeley, in 1984. Following postdoctoral work at the University of Pennsylvania, she held faculty positions at the University of Rochester (1987-1999) and Kansas State University (1999-2003) before becoming one of the founding faculty at the University of California, Merced, in 2003. Her primary research area has been resonance Raman spectroscopy, linear and nonlinear, but she has also worked in several other areas of spectroscopy including single-molecule and line-narrowed fluorescence, four-wave mixing, and time-resolved methods. She is a Fellow of the American Physical Society and the American Association for the Advancement of Science.
