Energy transfer and migration in fluorescent solutionsMagnetic field effects on dynamic behavior and chemical reactions of excited moleculesHigh pressure luminescence spectroscopy in polymersPrimary photophysical and photochemical processes in light-induced polymerizations: reactivity of the photoinitiatorSynthesis and properties of the polymers having coumarin dimer moietiesElectronic coupling and relaxation patters in polymersPhotoelectrochemical utilization of solar energy Photochemistry and Photophysics is a multi-volume set that presents a critical review of new developments that have occurred in the inorganic, organic, atmospheric, environmental, material, bio-and polymer fields of photochemistry and photophysics over the last decade. Specific topics covered in Volume III include photochemical processes at semiconductors, photoluminescence probes of porous solids, photoluminescence probes of polymer structures, and photomodification of cell membranes. Topics covered in Volume IV include magnetic fields in photochemistry, heterogenous photocatalysis by semiconductor powders, hydrophobic and hydrophyllic effects on photochemical and photophysical processes, and photoinitiators for free radical polymerization. The book provides essential information for students and researchers in photochemistry and photophysics.
