Structure and photodimerizations of 1-alkylthymines in single crystals.
1-Alkylthymine gave four kinds of crystals depending on the solvents used. Photodimerizations of 1-alkylthymine in single crystals were found to depend on the crystal structure. In inactive crystals, the terminal methyl group of alkyl chains approached to the double bond of thymine, and inhibited rotation of thymine bases during photodimerization.
