Presidential Young Investigator Award/Time Resolved Femtosecond Nonlinear and Coherence Spectroscopies of Liquids

Mark a . Berg博士获得了实验物理化学计划颁发的总统青年研究员奖，研究无序凝聚态物质的超快速过程。这些测量提供了有价值的见解，化学能的流动和重新分配，以及洞察各种化学反应的时间尺度。溶剂对化学反应后产物能量分布的影响将通过使用飞秒红外光谱来监测小分子解离后产物碎片的振动和取向状态来完成。与气相反应的详细信息进行比较将直接揭示溶剂在反应最终状态相互作用中的作用。

Dr. Mark A. Berg is supported by a Presidential Young Investigator award from the Experimental Physical Chemistry Program to study ultra-fast processes in disordered condensed matter. These measurements provide valuable insight into chemical energy flow and re-distribution as well as insight into the time scale of various chemical reactions. The influence of the solvent on the product energy distribution following a chemical reaction will be accomplished through the use of femtosecond infrared spectroscopy to monitor the vibrational and orientational states of product fragments following small molecule dissociations. Comparisons with the detailed information available for gas-phase reactions will directly reveal the role of the solvent in the final-state interactions of the reaction.
