Abstract

The interaction of pyrimidine with iodine when both are dissolved in a liquid crystal solvent has been studied. The considerable changes observed in the degrees of order of pyrimidine can be quantitatively attributed to complex formation between the nitrogen atoms and iodine along axes forming angles of 30Β° with the nitrogen–nitrogen axis and in the molecular plane. The complex formation does not affect measurably the proton and carbon positions of pyrimidine.

Electron transfer (ET) to Rh(III) complexes intercalated in DNA is known to initiate the photorepair of cyclobutane-type pyrimidine photodimers Pyr<>Pyr. We analyzed the energetics of the elementary steps of the resulting splitting reaction Pyr<>Pyr + Rh(III) + hΞ½ β†’ Rh(III) + 2Pyr based on results o
