HIGHLY-SENSITIVE RAMAN SPECTROSCOPY AT METAL/SOLUTION INTERFACES

Abstract

Attenuated total reflection (ATR) and Raman spectroscopy was studied to characterize the interfaces between Ag and liquid. When the incident angle of the laser beam coincides with the ATR dip, the surface-plasmon-polariton (SPP) of the silver film was excited resonantly and the Raman scattering intensity of the methanol showed a maximum.
