Photochemistry, physicochemical

Spectroscopy and Physical Chemistry of Retinal and Visual Pigments. Several reviews and symposium proceedings discuss the spectroscopic, photochemical, or physicochemical properties of retinal and related compounds, and of natural and model visual pigments derived from them. " " In addition, many papers have been published dealing with specific aspects of the spectroscopy (u.v., n.m.r., resonance Raman) of retinals and rhodopsins" or with aspects of the photochemistry and physical chemistry of retinal derivatives which may be relevant to the functioning of rhodopsin and other visual pigments. The bacterial purple... 

Another characteristic of modem coordination chemistry is the increasing reliance upon physicochemical methods unknown to Werner and his contemporaries. Simultaneously with an introduction of these newer techniques, emphasis shifted from preoccupation with qualitative studies of stmcture and stereochemistry to quantitative studies of thermodynamics, kinetics, and reaction mechanisms. Some areas of current research interest include unusual ligands, oxidation states and coordination numbers, solid-state chemistry, photochemistry, relationship between stmcture and reactivity, variable oxidation state, chelates, heteropoly complexes, organometalhc...
