内容介绍： 本课程的目标是要说明的光谱的小分子的气相：量子力学的哈密顿量模型的旋转、振动、电子结构；跃迁选择规则和相对强度；注重诊断模式和实验方法而非的教科书的光谱；模拟奥本海默近似（光谱扰动）；固定相近似；非简并微扰理论（quasidegenerate范弗莱克变换）；定性分子轨道理论（沃尔什图）；原子与分子光谱法。 The goal of this course is to illustrate the spectroscopy of small molecules in the gas phase: quantum mechanical effective Hamiltonian models for rotational, vibrational, and electronic structure; transition selection rules and relative intensities; diagnostic patterns and experimental methods for the assignment of non-textbook spectra; breakdown of the Born-Oppenheimer approximation (spectroscopic perturbations); the stationary phase approximation; nondegenerate and quasidegenerate perturbation theory (van Vleck transformation); qualitative molecular orbital theory (Walsh diagrams); the notation of atomic and molecular spectroscopy. 作者介绍： 麻省理工学院(Massachusetts Institute of Technology,MIT)是美国一所综合性私立大学。位于马萨诸塞州的波士顿,查尔斯河(Charles River)将其与波士顿的后湾区(Back Bay)隔开。MIT无论是在美国还是全世界都有非常重要的影响力,培养了众多对世界产生重大影响的人士,是全球高科技和高等研究的先驱领导大学。麻省理工学院的自然及工程科学在世界上享有极佳的声誉,其管理学、经济学、哲学、政治学、语言学也同样优秀。由于在学术方面的卓越成就,虽然MIT不是常春藤盟校成员,MIT也常被纳入Ivy Plus。 主讲人 Prof. Robert Field 内容截图：
