对硝基苯甲酸在水溶液和银胶中的紫外拉曼光谱

摘要

We record the accurate and reliable Raman spectra of p-nitrobenzoic acid (PNBA) in aqueous solution with ultraviolet excitation and the bands are attributed. We also report the phenomenon of surface Raman spectroscopy of PNBA in silver colloid without any enhancement in UV region. The possible mechanism of this phenomenon are discussed.%本文给出了紫外激发下的PNBA水溶液的拉曼光谱图,并对图中峰位做了相应的归属认证.本文还报道了PNBA在银胶中的表面非增强拉曼散射现象,并分析了导致该现象可能的原因.
