摘要
A quantum-chemical investigation has been carried out by the semiempirical AM1 method of the trans-cis photoisomerization mechanism of 4-[2-(2-chlorophenyl)vinyl]-6,6-dimethyl-2-oxo-1,2,5,6-tetra- hydropyridine-3-carbonitrile. It was shown that the isomerization process proceeds in the excited singlet state S1 by rotation of the 2-chlorophenyl substituent around the C(2)–C(3) bond. Electronic absorption spectra of the isomers were calculated by the INDO/S method Transitions caused by exitation of an electron from HOMO to LUMO were characterized by the greatest intensity.
