Abstract
Abstract The surface-enhanced Raman spectroscopy of 2,6-dibromopyridine and 2,5-dibromopyridine in silver hydrosol has been studied. A satisfactory correlation has been observed between the normal Raman spectra in aqueous solution and their surface-enhanced Raman (SER) spectra in silver hydrosol. The prominent features in the SER spectra of the compounds are the strongly enhanced peaks at 1175 and 1369 cm −1 due to (py)CBr and (CC,CN)(py) stretching vibrational modes respectively in 2,6-dibromopyridine and almost no enhancement of intensities in those vibrations in 2,5-dibromopyridine.
