In this project, funded by the Experimental Physical Chemistry Program of the Chemistry Division, Prof. Lawrence D. Ziegler of Boston University will conduct a series of experiments to investigate the electronic and nuclear responses to impressed strong laser fields. Three tasks will be pursued: 1) ultrafast spectroscopic techniques will be used to investigate the solvation properties of supercritical fluids (SCFs); 2) a novel two-photon absorption technique will be developed; and 3) a new method for the characterization of short optical pulses will be implemented. The first of these consists of three sub-parts, namely: a) investigations of femtosecond infrared photon echoes of SCF solutions; b) investigations of the optical heterodyne-detected (OHD) rotational Raman responses of hydrogen in SCFs; and c) a study of the polarization specific OHD Raman responses of neat SCFs. This research will be done in collaboration with theory groups and an experimental physics group. Students and postdoctoral research associates will participate in this research and will be trained in one of the forefront areas of contemporary physical chemistry in preparation for advance study or employment in academia, industry, or government laboratories.

在这个项目中，由化学部实验性化学计划资助，波士顿大学的劳伦斯·D·齐格勒教授将进行一系列实验，以调查对强烈激光领域印象深刻的电子和核反应。 将执行三个任务：1）超快光谱技术将用于研究超临界流体（SCF）的溶剂化特性； 2）将开发一种新型的两光子吸收技术； 3）将实现一种表征短光脉冲表征的新方法。 其中的第一个由三个子部分组成，即：a）对SCF溶液的飞秒红外光子回波的研究； b）研究SCF中氢的光学杂项检测（OHD）旋转拉曼反应的研究； c）研究整齐的SCF的极化特异性OHD拉曼反应。 这项研究将与理论组和实验物理小组合作进行。 学生和博士后研究伙伴将参加这项研究，并将在当代物理化学的最前沿培训，以准备在学术界，工业或政府实验室进行预先学习或就业。
