摘要：

Experimental results are provided that correlate the differential interfacial capacitance of electrode surfaces to the pH properties of surface-confined monolayers of molecular bases such as 4-mercaptopyridine and 4-aminothiophenol. In accord with theoretical predictions, the fractional degree of monolayer protonation is shown to be a function of the solution pH and the electrode potential.
