Richard Stratt of Brown University is supported by an award from the Theoretical and Computational Chemistry program for research to develop theoretical and computational methods to simulate and understand ultrafast spectroscopic studies of solvation dynamics. These studies are focused on investigating the response of the solution to electronic excitation and invoke a three-time portrait of the solution dynamics rather than the traditional two-time picture.With the advent of ultrafast lasers, scientists are now able to study the details of solvent reorganization that occurs whenever a chemical reaction takes place. This work is helping to broaden our understanding of exactly how those processes occur. In addition to the scientific broader impact, the work is having a broader impact societally through Stratt's efforts in communicating the value and excitement of scientific research to the public through a series of general interest presentations.

布朗大学的理查德·斯特拉特得到了理论和计算化学项目颁发的奖项的支持，该奖项旨在开发理论和计算方法来模拟和理解溶剂化动力学的超快光谱研究。这些研究集中于研究溶液对电子激发的响应，并调用溶液动力学的三次画像，而不是传统的两次画像。随着超快激光的出现，科学家现在能够研究每当发生化学反应时发生的溶剂重组的细节。这项工作有助于扩大我们对这些过程究竟是如何发生的理解。除了科学上更广泛的影响外，这项工作还产生了更广泛的社会影响，斯特拉特努力通过一系列普遍感兴趣的演示向公众传达科学研究的价值和兴奋。
