Development of Experimental and Theoretical Crystal Lattice Organic Photochemistry:  The Quantitative Cavity. Mechanistic and Exploratory Organic Photochemistry

The photochemistry of organic reactants in the crystalline state has a long history. What has been lacking is comprehensive theory defining what controls the course of these reactions which quite often afford products not obtainable in solution. Also lacking has been solid-state rearrangement chemistry with accompanying theory. In our research over the past two decades we have developed theoretical treatments of solid-state reactivity. This report describes the development of this research from its primitive beginnings to the present.
