✦ Synopsis

Surface enhanced Raman scattering (SERS) studies of 1-aminoanthraquinone (AAQ), lmethylaminoanthraquinone (MAAQ) and I-propanolaminoanthraquinone (PAAQ) adsorbed on silver colloidal particles have been made. The observed SERS spectra have 8.8 and 11 new bands for AAQ, MAAQ and PAAQ, respectively. The procedure used to prepare the silver sol has an effect on the quality of the SERS spectra. In all the three samples, the intensity of bands due to carbonyl stretching and ring breathing modes is more pronounced. It is found that there is a downward shift in the frequency of the ring breathing mode in PAAQ due to bulky substitution.

## Abstract Surface‐enhanced Raman scattering spectra of 1‐phenyl‐5‐mercaptotetrazole (PMT) and of the corresponding sodium salt adsorbed on silver sols were recorded in the 3700–2800 and 1800–150 cm^−1^ regions. The SERS spectra obtained in both cases are the same, therefore it can be deduced that
