With two new Co-authors, V.Ramamurthy and J.C. Scaiano, Nick Turro has completely revised and updated his benchmark text Modern Molecular Photochemistry. The new text will present, at a level understandable by advanced undergraduates and postgraduates, the first totally, integrated theory of organic photochemistry, including the first visualization of the role of electron spin at all levels. In addition, chapters describing how experiment and theory can be applied to an understanding of the fundamental chronophers of organic chemistry will be presented. Ideal for 3rd year undergraduate and postgraduate students taking Organic Chemistry courses.
