摘　　要：在Ag胶中对吡啶分子进行了红外表面增强付立叶变换喇曼散射研究,发现增强因子为3.4×10~4,添加少量KCL时为4.5×10~5。还对吖啶橙和罗丹明B荧光分子进行了红外付里叶变换喇曼散射测量并与可见光下的表面增强喇曼光谱进行了比较。在此基础上讨论了红外付里叶变换喇曼的优缺点和应用前景。The enhanced factors were found to be 3.4 × 10~4 and 4.5× 10~5 for the pyrindine-Ag sol system without and with a small amount of KCI, respectively in the i.r.surface enhanced Raman scattering. Besides, the i.r Raman spectra of fluoreseent 吖啶橙 and rhodamine B were recorded. Based on these observahons, the applicability and advantage of i.r. Raman tech- nique over traditional Raman spertroscopy is discussed.
