The third edition of the Handbook of Photochemistry offers detailed overviews of the photochemical processes that occur in organic molecules and transition metal complexes, written by leading experts around the world. The authors maintain the highly regarded organization of data from previous editions while updating and expanding its tables with data pertaining to hundreds of new compounds. The book now contains sections focusing on metal complexes and organometallic compounds, offering photophysical and quenching data as well as reduction potential values, a key factor in photochemical electron transfer processes. It also features new information on light sources and filters, chemical actinometry, solutions to common problems in photoluminescence measurements, and lab-friendly techniques pertaining to experimental UV/visible spectroscopy and irradiation methodologies.
