At Caltech, we have recently adapted an electrospray\nionization mass spectrometer to selectively probe physicochem. phenomena on liq. surfaces. Thus, together with theory and\nexpts. we have demonstrated that (1) anions present at air-water interface can electrostatically preorganize surrounding water\nmols. to facilitate proton transfer events, (2) the neg. charge of the air-water interface is due to the presence of excess OH- at\nthe aerial interface with a point-of-zero-charge at pH \u223c 3, and (3) rate enhancements obsd. in the proton catalyzed reactions at\nfluctuating aq. interfaces is due to inadequate hydration of hydronium, H_3O+. These findings should further our understanding\nof atm. chem., colloidal science, 'on-water' and enzymic catalysis and proton transfer reactions along and across membranes,\nincluding fuel cells and cellular processes.",
