Spectroscopy and Dynamics in Gas Phase Metal Ion Complexes

乔治亚大学的Michael Duncan教授在实验物理化学项目的支持下，对气相金属离子簇进行实验研究。通过激光汽化技术制备的金属/配体配合物可作为金属-配体结合、金属离子溶剂化和表面吸附键合的模型。利用光学和红外激光光解离光谱和ZEKE-PFI光电子能谱等多种光谱技术测定配合物的结构和解离能，其中新的红外双共振实验引起了人们的兴趣。这些配合物包括镁、钙和铝与水、氨和甲醇相互作用的配合物。扩展到更大的有机金属配合物，如金属-冕烯也被提出。这一建议的一个成功的结果将是金属配体配合物中键合的准确和详细的图片。这些知识在材料和生物化学方面有重要的应用。

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.
