Condensed-Phase Molecular Spectroscopy and Photophysics

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.
