- W1198625481 abstract "摘要 本文用拉曼峰强求得时间分辨键极化率的方法,分析了哒嗪分子在银电极上的表面增强拉曼谱图.哒嗪分子在不同电位下的键极化率和其弛豫特征时间,显示该分子的吸附点为两个氮原子,以及该分子体系的电荷转移机制机理,包括共轭的效应.对于具有良好拉曼谱图的体系,这个方法具有普适性. 关键词: 哒嗪 / 拉曼峰强 / 时间分辨键极化率 / 弛豫特征时间 Abstract The temporal molecular bond polarizabilities of pyridazine molecule absorbed on Ag electrode were explored from its surface enhanced Raman intensities, showing that the two nitrogen atoms are the absorption sites and the enhancement is dominated by the charge transfer mechanism. The behaviors of the charges on the skeletal bonds were demonstrated under various applied voltages, which shows the conjugation effect. This algorithm is universal for the surface systems as long as their Raman spectra are available. Keywords: pyridazine / Raman intensity / temporal bond polarizability / relaxation of bond polarizability 作者及机构信息 房超1, 吴国祯2 (1)清华大学核能与新能源技术研究院,北京 100084; (2)原子分子纳米教育部重点实验室,清华大学物理系,北京 100084 基金项目: 教育部重点实验室基金(批准号:306020),高等学校博士学科点专项科研基金(批准号:20060003050),国家自然科学基金(批准号:20773073)资助的课题.
