Popis: Quantum chemical calculations of the electronic and geometric structure of the HOO-N=N-OOH intermediate in the activation reaction of molecular nitrogen are performed by the density functional theory method at the B3LYP/6-311++G(3df,3pd) level. For HOO-*N=N*-OOH isotopomers with respect to nitrogen the spectroscopic parameters of the intermediate are characterized, which indicate the possibility of its experimental detection. The reactivity of the high energy state HOO* (2 A′) in the activation of N2 is analyzed. The possibility of the generation of singlet oxygen O2 (1Δ g ) is considered in the dimerization of radicals with the ground state HOO (2 A″) followed by the sensitization of excited HOO* (2 A′). A substantiated process of bonding of molecular nitrogen is given as an example of the self-organization of a chemical system in the activation of a hard-to-oxidize N2 substance.
