Abstract Normal and heavy water are solvents most commonly used to study the isotope effect. The isotope effect of a solvent significantly influences the behavior of a single molecule in a solution, especially when there are interactions between the

Photodestruction of 2-(pyrazin-2′-yl)-1H-indole and 2,5-di(1H-indol-2′-yl)pyrazine involves singlet oxygen generation and its rapid insertion into the indole ring with the formation of benzoxazinone derivatives: 2-(pyrazin-2-yl)-4H-3,1-benzoxazin

The UV-induced oxidation of 2-(1′H-indol-2′-yl)-[1,5]naphthyridine acetonitrile solution in the presence of air leads to the formation of 2-(1,5-naphthyridin-2-yl)-4H-3,1-benzoxazin-4-one as a major product and N-(2-formylphenyl)-1,5-naphthyridin

Parent, unsubstituted free base hemiporphycene, a constitutional isomer of porphyrin, was synthesized only a few years ago, and the detailed characterization of vibrational structure is lacking. We studied vibrations of hemiporphycene using site-sele
