Effect of oxygen on the excited state of complex organic molecules

Abstract

This article provides an analysis of the electronic structure of 2 O oxygen molecule. The mechanism of quenching of aromatic hydrocarbons luminescence affected by an oxygen molecule is analysed. Since the interaction of triplet oxygen with singlet organic molecules is not possible, an analysis of interaction at excited singlet states is carried out. The interaction of the oxygen molecule with complex organic molecules at excited electron states has a number of interesting effects, the reason of which is not completely clear. It is particularly important in nanostructures, when the size of the particle interaction area is comparable to the size of the reagents. The main parameters obtained by calculation, confirming the mechanism of the spinorbital interaction are cited
