Laser Spectroscopy of Ions and Clusters

有了这个更新的建议，教授理查德Saykallly寻求支持他的离子和水分子簇的激光光谱学的研究。 拟议中的研究将细化和扩展水二聚体的潜力，通过表征和建模的平面振动预计将在500 cm-1附近看到。 然后，将使用改进的二聚体势来计算水三聚体中的三体相互作用。 这些潜力将用于先进的散装水模拟，与大卫钱德勒的小组在伯克利分校的合作。 其他方面，如实验检查（H2O）8，水合质子簇，EXAFS的液体水，和核苷酸碱基水合物将进行实验研究。改进的液态水和水溶剂化模型将对蛋白质结构和其他生物分子的建模产生影响。 对液态水的进一步了解仍然是分子物理学和凝聚态化学中一个重要的未解决的问题。

With this Renewal proposal, Professor Richard Saykallly seeks support for his research on laser spectroscopy of ions and water clusters. The proposed research will refine and extend the water dimer potential, by characterizing and modeling out of plane librational vibrations expected to be seen near 500 cm-1. The refined dimer potential will then be used to calculate three-body interactions in the water trimer. These potentials will then be used for advanced bulk water simulations, in collaboration with David Chandler's group at Berkeley. Additional aspects, such as experimental examination of (H2O)8, hydrated proton clusters, EXAFS of liquid water, and nucleotide base hydrates will be examined experimentally. Improved models for liquid water and aqueous solvation will have impact in the modeling of protein structures and other biological molecules. A greater understanding of liquid water remains an important unsolved problem in molecular physics and condensed matter chemistry.
