Preferred Label : Dauben–Salem–Turro rules;
IUPAC definition : Set of rules proposed in 1975 to classify photochemical reactions based on correlation
diagrams and under the assumption that all photochemical processes are controlled
by the generation of primary products with characteristics of diradicals, i.e., considering
the physical fact that the initial single excitation separates two electrons of a
pair into two distinct orbitals. The reactions are classified according to their
u topicity /u , i.e., the total number and nature of available radical sites generated
in the primary photochemical product.;
