The structure of an adduct between guanine and the carcinogen acetylaminofluorene has been examined in the solid state by X-ray crystallography, and in solution by NMR techniques. The observed conformations have been compared with predictions from energy calculations and their relevance to models of adducts with DNA has been examined.
