摘要/Abstract

摘要： 用表面增强拉曼光谱的方法研究 4-羟基--甲基-1,3,3a,7-四氮茚(TAI)在金属银上的吸附.实验表明TAI分子是通过分子上的N原子以化学吸附的方式吸附在银电极上.电极处理的氧化-还原循环次数并不影响振动频率,但在一定范围内对表面增强拉曼光谱的吸收强度有明显影响.

关键词: 4-羟基-6-甲基-1,3,3a,7-四氮茚, 表面增强拉曼光谱, 氧化-还原循环

Abstract: Adsorption of 4-hydroxy-6-methyl-1,3,3a,7-teraazaindene(TAI)on a silver surface was investigated by surface enhanced Raman spectroscopy(SERS).In the present system,TAI molecule is chemisorbed on the surface of silver electrode.The N atom of TAI plays the principal role of adsorption on the silver electrode.It is concluded that TAI molecule is adsorbed on the silver electrode by edged-on mode.Although the number of ORC does not affect the frequencies of vibration,it obviously affects the intensities of SERS.

Key words: 4-hydroxy-6-methyl-1,3,3a,7-teraazaindene, surface-enhanced Raman spectroscopy, oxidation-reduction cycle
