Second harmonic a.c. voltammetry of surface-bonded pyrazolines

Abstract

Second harmonic a.c. voltammetry is shown to have high promise as an electroanalytical tool for the study of reactive species chemically bonded to an electrode surface. Even with a low density of surface sites, the strong discrimination against nonfaradaic currents permits useful data to be obtained. Results from studies using 2-pyrazoline structures surface bonded to SnO 2 are given and discussed.
