Abstract

The vibrational sum frequency generation (SFG) spectra of the air–liquid interface of H2SO4–H2O solutions over a wide range of concentrations are measured in the SO stretching region (1000–1300 cm−1). The analogy of the concentration dependence of Raman and SFG is indicative of a nearly identical behavior of the first acid dissociation at the air–liquid interface as in the bulk.
