Professor Mary Berry of the University of South Dakota is supported by the Experimental Physical Chemistry Program to study the excited state decay dynamics of vapor phase lanthanide complexes. These experiments represent the first application of spectroscopic molecular beam methods to the case of lanthanide complexes, complementing studies by others on alkali, alkaline earth and transition metals. Resonance Enhanced Multiphoton Ionization (REMPI) spectroscopy will be employed to investigate europium (III) complexed with organic ligands. The initial focus will be on the feasibility of REMPI detection in these molecular systems. These gas phase studies will allow the spectroscopy and dynamics to be determined without the convoluting factors of crystal strain and solvent and ion interactions. Lanthanide compounds are important in energy applications and are used as materials for lasers, for example. A more thorough understanding of the spectroscopy of these compounds will prove useful in developing new optical materials. The PI has an excellent mentoring record including Native American students.

南达科他州大学的玛丽贝瑞教授受到实验物理化学计划的支持，研究气相镧系元素络合物的激发态衰变动力学。 这些实验代表了光谱分子束方法首次应用于镧系元素络合物的情况，补充了其他碱金属，碱土金属和过渡金属的研究。 共振增强多光子电离（REMPI）光谱将用于研究铕（III）与有机配体的配合物。 最初的重点将是在这些分子系统中的REMPI检测的可行性。 这些气相研究将允许光谱和动力学被确定没有晶体应变和溶剂和离子相互作用的卷积因素。 稀土化合物在能源应用中非常重要，例如用作激光器材料。 对这些化合物的光谱学有更深入的了解将有助于开发新的光学材料。PI拥有出色的指导记录，其中包括美洲原住民学生。
