Ultraviolet (254 nm) irradiation of thymidine in frozenaqueous solution produces three dimeric products referred to as Tdi, Td3, and Td4, in addition to the cyclobu-tane-type dimers. BothTdi and Td4 have ultraviolet absorp-tion maxima at 316 nm; Td3 has an absorption maximum at 267 nm. These dimeric products are not converted into thymidine by irradiation in aqueous solution at 254 nm. Mild acid hydrolysis of Tdi gives 5-hydroxy-6-4'-[5'-methylpyrimidin-2'-one) dihydrothymine (TT adduct). Acid hydrolysis of Td3 gives 5-thyminyl-5, 6-dihydrothymine (TDHT). On
