中文摘要	CO吸附在经方波电势处理后的纳米结构Pt金属膜电极上可观察到异常红外效应 (AIREs) .在实验基础上用粒子间的相互作用和电子空穴衰减机理分析、模拟了AIREs ,表明Pt金属表面的纳米岛状结构增强了CO分子间及CO分子与纳米结构表面的相互作用 ,电子空穴衰减引起的能量转移和粒子间相互作用的增强可以导致异常红外吸收谱线变化特征的出现 .; The abnormal IR effects(AIREs) of the adsorption of CO on electrodes made of Pt nanostructured thin films generated in square wave potential treatment were observed. Based on the experimental results,the AIREs were analysed and simulated by taking into consideration of the interparticle interaction and the electron-hole damping. The results illustrate that the islanded nanostructured Pt surfaces give rise to the interactions between CO molecules as well as between CO molecules and nanostructured Pt surface. The energy transfer due to electron-hole damping and the enhancement of interparticle interaction are the important cause of the changes of IR absorption spectra.; 【作者单位】厦门大学物理系软凝聚态研究室；厦门大学固体表面物理化学国家重点实验室；厦门大学固体表面物理化学国家重点实验室厦门361005；集美大学理学院物理系；厦门361021；厦门361005；厦门361005；【作者英文名】Huang Xiao-Jing 1)2) Wu Chen-Xu 1) Chen You-Jiang 3) Lin Hai 1) Jiang Dong-Hua 1) Sun Shi-Gang 3) 1)(Department of Physics,Xiamen University,Xiamen 361005,China) 2)(Department of Physics,Schorl of Science, Jimei University,Xiamen 361021,China) 3)(Sta
