WebDescription. Photochemistry — 6 is a collection of plenary lectures presented at the Sixth International Symposium on Photochemistry held in Aix-en-Provence, France, on July 19-23, 1976. Contributors focus on the photochemistry of a variety of compounds and substances, including bichromophoric compounds, heterocycles, and metal carbonyls. Webphotochemical reaction, a chemical reaction initiated by the absorption of energy in the form of light. The consequence of molecules ’ absorbing light is the creation of transient excited states whose chemical and physical properties differ greatly from the original molecules.
