We have examined changes in the electronic structure of magnetite (100) and (111) surfaces after reaction with water vapor (p(H2O) ranging from 10-9 to 9 Torr) and liquid water at 298 K using chemical shifts in the O 1a core-level photoelectron spectra obtained with a synchrotron radiation source. The surfaces were prepared in ultra high vacuum from natural magnetite crystals. We found that the vapor pressure, p(H2O), at which first reacts with magnetite is similar for the two surfaces (
