Quantum-chemical investigation of the 1-methylthymine dimer photoproduct: Pyrimidine-(6-4)-pyrimidone adduct [PDF]
One of the products of a photochemical reaction induced by UV irradiation of 1-methyltimine dimmer is pyrimidine(6-4)pyrimidone. Due to the low yield of this product, it is difficult to examine its geometry and vibrational spectrum.
