Spectroscopic characterization of elementary species in water-mediated chemistry using size-selected clusters

在这个由化学系实验物理化学项目资助的奖项中，耶鲁大学的Mark A.Johnson教授和他的研究生同事将研究质子化水团簇和被水团簇溶剂化的简单分子离子的振动光谱。此外，约翰逊教授和他的团队将开始研究整体电中性系综中的水介电电荷分离。这项研究的结果有望提供有关质子溶剂化性质的基本信息--质子是一种普遍存在的物种，在大气化学和分子生物学等不同领域都很重要。除了这项研究得到支持的更广泛的科学影响外，约翰逊教授的学生将接受广泛的实验物理化学培训，并将受益于与其他小组(理论和实验)积极合作，开展相关项目的研究。

In this award, funded by the Experimental Physical Chemistry Program of the Chemistry Division, Prof. Mark A. Johnson of Yale University, and his graduate student colleagues will investigate the vibrational spectra of protonated water clusters and simple molecular ions solvated by water clusters. In addition, Prof. Johnson and his group will begin an investigation of water-mediated charge separation within overall electrically neutral ensembles. The results from this research are expected to provide fundamental information on the nature of the solvation of the proton -- a ubiquitous species that is important in fields as disparate as atmospheric chemistry and molecular biology.Besides the broader scientific impacts of the research being supported, Prof. Johnson's students will receive broad training in experimental physical chemistry and will benefit with active collaborations with other groups (both theoretical and experimental) conducting research on related projects.
