	abstract = {Sulfur dioxide reactions with calcium carbonate interfaces at 296 K in the presence and absence of adsorbed water result in the formation of adsorbed sulfite and sulfate.  The extent of reaction is significantly enhanced, approx. five- to ten-fold for particulate and single crystal CaCO3 (calcite), resp., in the presence of adsorbed water between 30 and 85\% RH.  At. force microscopy following the reaction shows that adsorbed water facilitates surface reactivity by enhancing the mobility of surface ions, giving rise to the formation of nanometer sized product crystallites approx. 1 nm in height.  Simultaneous with the formation of these crystallites is pitting and etching of the underlying substrate, which occurs preferentially in the vicinity of monoat. surface steps.  In the absence of water, there is little pitting and no evidence for the formation of crystallites.  X-Ray photoelectron core and valence band spectra confirm the presence of two sulfur adsorbed species, SO2-3 and SO2-4, with nearly equal amts. of SO2-3 and SO2-4 in the absence of adsorbed water and approx. five times more SO2-3 relative to SO2-4 in the presence of adsorbed water.  From these data, it is proposed that the nanometer-sized crystallites are composed primarily of CaSO3. [on SciFinder(R)]},
