This is a combined theoretical and experimental project in Physical Chemistry to study and describe the excited electronic states of atoms and molecules. In the experimental part, polarized light will be used to first excite and then ionize atoms and the molecules. The angular and energy distributions of the photoelectrons will be analyzed to determine the degree of electron correlation in the initially excited electronic state(s) of atoms. For atoms, the theoretical thrust of this research is to adequately describe this correlation. Once atoms are adequately described, the phenomenological theory of the angular and energy distributions of the photoelectrons will be extended to molecules and experimentally tested in an investigation of the angular and energy distributions of photoelectrons emitted from molecules. The goal of this research is to better understand the dynamics of the interactions between an electron and the molecular core to which it is bound, hence to better understand chemical bonding.

这是物理化学中的一个理论和实验相结合的项目，旨在研究和描述原子和分子的激发电子态。 在实验部分，将使用偏振光首先激发然后电离原子和分子。 将分析光电子的角度和能量分布，以确定原子初始激发电子态中的电子相关程度。 对于原子来说，这项研究的理论主旨是充分描述这种相关性。 一旦原子被充分描述，光电子的角度和能量分布的现象学理论将扩展到分子，并在从分子发射的光电子的角度和能量分布的研究中进行实验测试。 这项研究的目的是更好地了解电子与其所结合的分子核心之间相互作用的动力学，从而更好地了解化学键合。
