Here, we show that a combined atomic force microscopy/scanning tunneling microscopy (AFM/STM) experiment can both distinguish neutral O(2) molecules in the triplet state from negatively charged (O(2))(-) radicals and charge and discharge the molecules at will. By measuring the chemical forces above the different species adsorbed on an anatase TiO(2) surface, we show that the tip-generated (O(2))(-) radicals are identical to those created when (i) an O(2) molecule accepts an electron from a near-surface dopant or (ii) when a photo-generated electron is transferred following irradiation of the anatase sample with UV light. Kelvin probe spectroscopy measurements indicate that electron transfer between the TiO(2) and the adsorbed molecules is governed by competition between electron affinity of the physisorbed (triplet) O(2) and band bending induced by the (O(2))(-) radicals. Temperature-programmed desorption and X-ray photoelectron spectroscopy data provide information about thermal stability of the species, and confirm the chemical identification inferred from AFM/STM.
