Abstract

This communication reports, for the first time, the dependence of the SERS intensities under resonant CT conditions (SERS-CT) on the electrode potential. SERS-CT intensities have been estimated from the properties of S(0)-CT(i) transitions ranging between 200-1200 nm of selected [Ag(n)-pyridine](q) and [Ag(n)-pyrazine](q) complexes.
