✦ Synopsis

In view of their biological significance , photoproducts of nucleic acids and related substances have received considerable attention in recent years. X-ray analyses (1) have revealed their structures and have provided detailed information about their geometry. Although the photochemistry of erotic acid s and its derivatives has been studied by several people (2), the structure of the major photoproduct has been assigned only Indirectly as a cyclobutane dlmer. Recent mechanistic studies on the photochemistry of orotlc acid and its methyl ester E (3,4) make the absolute characterization
