Book Description

Photophysical and Photochemical Properties of Aromatic Compounds is the first book to collect and classify all available quantitative data on the photochemistry and luminescence of aromatic compounds. Compounds are classified by both spectral-luminescent (e.g., extinction coefficients, energies and lifetimes of lower excited states) and photochemical properties. In addition, all of the quantum yields available have been collected. The variety of photochemical reactions of aromatics is examined based on eight types of elementary monomolecular and bimolecular photochemical processes. Aromatic compounds are grouped into eight categories, and the book analyzes the possibilities of occurrence of all types of elementary photoprocesses.
