摘要：

H2O2 reacts with rutile TiO2 powder forming not only surface O-2(-) anions but also two newly identified surface S = 1 triplet radical anion pairs composed of two interacting O- ...O- centers characterised by the EPR spin Hamiltonian parameters of g(iso) = 2.0104 and D = 13.7 mT for triplet 1 and g(iso) = 2.0064 and D = 12.7 mT for triplet 2.
