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.
