反式肉桂酸和反式邻香豆酸的SERS光谱

STUDY ON THE SERS SPECTRA OF trans-CINNAMIC AND trans-o-HYDROXYCINNAMIC ACIDS ADSORBED ON SILVER FILM

首次记录了反式肉桂酸和反式邻香豆酸两种具有大π键电子结构的平面型分子在银膜上的SERS谱,讨论了它们在银膜表面上的吸附方式,并对这类分子在SERS现象中的模选择增强机制做了初步探讨。

In this paper we reported for the first time the SERS spectra of molecules of trans-cinnamic and trans-o-hydroxycinnamic acids adsorbed on silver film, discussed adsorption geometry of these molecules on silver film surface and gave a gualitative explanation of the relationship between SERS effect and molecule vibration modes.
