In this award the Experimental Physical Chemistry Program of the Division of Chemistry supports the development of a fundamental chemical sciences research effort in the group of Professor Niels Damrauer at the University of Colorado to understand how charge and energy flow in complex condensed-phase molecules following absorption of light. Femtosecond pulse-shaping methodologies will be called upon to interrogate and control photochemical pathways in novel coordination complexes. Systems exhibiting photoinduced electron transfer reactivity are selected and new metal complexes are synthesized wherein internal motions are expected to modulate the rate of a photoinduced electron transfer reaction. Photochemical control is expected if adaptively shaped laser fields can manipulate these motions. Additional systems are developed that exhibit excited-state relaxation pathways competing with electron transfer. This aspect of the program aims to develop spectroscopic methods for studying dynamical phenomena at reactive branching points between productive and non-productive channels. Finally, efforts are made to develop pulse-shaping two-dimensional electronic spectroscopy of inorganic chromophores and to link the observations to both opportunities and mechanisms for control. In the educational outreach component of this program, curricula relating to sustainable energy production are being developed for dissemination to middle school students in Colorado and to assist in professional development for teachers of grades 5-8. The societal and environmental urgency of the topics considered should motivate young minds to engage in fundamental scientific exploration and to seek further scientific training in high school.

在该奖项中，化学系的实验物理化学项目支持科罗拉多大学 Niels Damrauer 教授小组开展基础化学科学研究工作，以了解吸收后复杂凝聚相分子中的电荷和能量如何流动光。飞秒脉冲整形方法将被用来询问和控制新型配位复合物中的光化学途径。选择表现出光致电子转移反应性的系统并合成新的金属络合物，其中预期内部运动调节光致电子转移反应的速率。如果自适应形状的激光场能够操纵这些运动，则有望实现光化学控制。开发了其他系统，这些系统表现出与电子转移竞争的激发态弛豫路径。该计划的这一方面旨在开发光谱方法来研究生产性通道和非生产性通道之间的反应分支点的动态现象。最后，努力开发无机发色团的脉冲整形二维电子光谱，并将观察结果与控制机会和机制联系起来。在该计划的教育推广部分，正在开发与可持续能源生产相关的课程，以向科罗拉多州的中学生传播，并协助 5-8 年级教师的专业发展。所考虑的主题的社会和环境紧迫性应该激励年轻人参与基础科学探索并在高中寻求进一步的科学培训。
