四氢吡咯吸附在银膜表面上的激光喇曼散射效应实验研究

THE EXPERIMENTAL STUDY OF LASER RAMAN SCATTERING EFFECT OF PYRRQLIDINE ADSORBED ON THE ON THE SILVER FILM

本文研究了0.05mol/L四氢吡咯/0.10mol/LKCl体系吸附在化学沉积银膜上的表面增强喇曼散射(SERS)光谱。通过与正常喇曼谱比较,发现四氢吡咯吸附在化学沉积银膜上存在较强的SERS增强效应,并且一些谱带的位置发生了漂移。实验结果表明,四氢吡咯和银膜之间存在着强烈的相互作用。

This paper presents the SERS spectrum of 0.05 mol/L pyrroline/0.10 mol/L KCI system adsorbed on the chemically deposited silver film. Comparing with the normal Raman spectrum, we find that there exists stronger enhancement effect and some bands shfts for SERS spectrum of pyrrolidine adsorbed on the chemically deposited silver film. Experimental results show that there are intensive interactinns between pyrrolidine and silver film.
