Spectroscopy and Dynamics in Gas Phase Metal Ion Complexes

格鲁吉亚大学的Michael邓肯教授在实验物理化学计划的支持下对气相金属离子簇进行实验研究。 通过激光蒸发技术产生的金属/配体络合物作为模型的金属-配体结合，金属离子溶剂化和表面吸附物键合。 各种光谱，包括光学和红外激光光解离光谱和ZEKE-PFI光电子能谱被用来确定的结构和离解能的配合物，与新的红外双共振实验吸引了很大的兴趣。 络合物包括镁、钙和铝与水、氨和甲醇相互作用的络合物。 还提出了对更大的有机金属络合物如金属-晕苯的扩展。这一提议的成功结果将是金属配体络合物中键合的准确和详细的图像。 这些知识在材料和生物化学中有重要的应用。

Professor Michael Duncan of the University of Georgia is supported by the Experimental Physical Chemistry program to perform experimental studies on gas phase metal ion clusters. The metal/ligand complexes produced via laser vaporization techniques serve as models for metal-ligand binding, metal ion solvation and surface-adsorbate bonding. Various spectroscopies including optical and infrared laser photodissociation spectroscopy and ZEKE-PFI photoelectron spectroscopy are utilized to determine structures and dissociation energies of the complexes, with the new IR double resonance experiments drawing much interest. The complexes include those of magnesium, calcium and aluminum interacting with water, ammonia and methanol. Extensions to larger organometallic complexes such as metal-coronene are also proposed. A successful outcome of this proposal would be an accurate and detailed picture of the bonding in metal-ligand complexes. There are important applications of such knowledge in materials and biological chemistry.
