## Abstract Surface‐enhanced Raman spectra of 2‐mercaptobenzoxazole (MBO) adsorbed on silver hydrosol were obtained. From the comparison of the SER and normal Raman spectra, both in the solid state and in NaOH solution, it can be deduced that the molecule is dissociatively adsorbed on the silver so
The surface-enhanced Raman (SER) scattering of p-nitroaniline adsorbed on silver colloids was investigated and compared with previous results obtained on a silver electrode. The SER spectra change signiÐcantly on varying the pH of the colloidal dispersions and correspond to di †erent adsorbed specie
