摘要

Abstract: There were received SERS spectra of para- metoxystyrylphtalylium (MSPh) with different roughness of surface of thin silver films (TSF). Spectra were received when applying solutions on the TSF directly and after preliminary acetonitrile treatment. There were discovered considerable differences of SERS spectra of MSPh adsorbed from ethanol solution on annealed and non-annealed TSF (after acetonitrile treatment).!8
