2Pa Cu2+ and two equivalent O- ions, having covalent contributions to the Cu-O bonding, in contrast to Cu(O2), which is formulated as an interaction between Cu+ and O2- ions, a tight-ion pair, having nonequivalent oxygen atoms with the odd electron residing mainly on the dioxygen moiety, that is , mono-η1-superoxocuprous(I).Attention is focused on mechanistic aspects of the copper atom-dioxygen photochemical reaction, especially the differences in the reactivity of the Cu atom in its ground 2S and excited 2P and 2D electronic states.It is proposed that the generation of CuO2 following the 2P2D relaxation, diffusion of a long-lived Cu 2D atom to an O2 molecule, and insertion of a Cu 2D atom into O2 to yield CuO2.This should be contrasted with 2S Cu atoms reacting spontaneously with a neighboring O2 molecule via electron transfer to form Cu(O2).
