Spectroscopic Studies of (a) Defect Activities of Icelike Solids and (b) Structures of Ion-Pair Solvents

这项研究是实验物理化学计划的一部分，旨在了解氢键系统中的缺陷现象。 这项研究将对冰晶生长和成核机制产生新的见解，这是一个对从保护农作物到了解质子穿过细胞壁运输的重要机制等技术都很重要的领域。 将研究界面效应对表面附近缺陷活动的影响，以建立缺陷活动与冰状结构从亚稳态生长的能力之间的关系。 还将探索质子和非质子溶剂中的离子对研究。 实验将使用红外和拉曼光谱技术在室温和低温系统上进行。 重点将放在基质溶剂化光谱与其他人获得的玻璃化水性体系的相应光谱之间的比较。

This research, part of the Experimental Physical Chemistry Program, is designed to understand defect phenomena in hydrogen bonded systems. This research will lead to new insights into the mechanisms of ice crystal growth and nucleation, a field of importance to technologies varying from protection of agricultural crops to the understanding of the mechanisms of importance in transport of protons through cell walls. The influence of interfacial effects on defect activities near surfaces will be studied to establish the relationships between defect activities and the ability of ice like structures to grow from metastable phases. Ion pair studies in both protic and aprotic solvents will also be explored. The experiments will be performed using the techniques of infrared and Raman spectroscopy on room and low temperature systems. Emphasis will be paid to comparisons between matrix solvation spectra and the corresponding spectra obtained by others for vitrified aqueous systems.
