Intellectual Merit: Support from the NSF Catalyzing New International Collaborations Program will establish a new collaboration between two groups who have developed different methods for studying the stereodynamics of elastic and inelastic rotational energy transfer (RET): the Halpern group at Howard University in Washington, DC and the McKendrick-Costen group at Heriot-Watt University in Edinburgh, Scotland. The expertise and instrumentation at Howard and Heriot Watt are complementary. The award will support travel of Prof. Halpern and students to Heriot-Watt to undertake proof of concept experiments. The goal is to prepare oriented samples of vibrationally excited, ground state CN radicals using simulated emission pumping and probe the prepared states by frequency modulated transient absorption spectroscopy. Broader Impacts: This project brings together two groups that have contributed to the study of collisional polarization transfer and quenching. The collaboration will substantially advance our understanding of this basic process, which is a severe test of the ability to calculate potential energy surfaces and carry out dynamics on them. It will provide qualitative insights in areas such as atmospheric and combustion chemical dynamics where small radical energy transfer and reactions are basic. Both sides of the collaboration view this preliminary work which will support further proposals, publications and student training. The international nature of the collaboration advances NSF?s goal of global science. Howard University is an HBCU, serving African Americans and with a substantial number of international students of African descent. The new collaboration, involvement of Howard students in the research visits and the opportunities for them that will grow out of the collaboration in the future will support NSF goal of growing participation from groups that are under-represented in STEM fields in the US as well as having a global outreach.

智力优势：来自NSF催化新的国际合作计划的支持将建立两个小组之间的新的合作，这两个小组已经开发了不同的方法来研究弹性和非弹性旋转能量转移（RET）的立体动力学：位于华盛顿的霍华德大学的Halpern小组和苏格兰爱丁堡赫瑞瓦特大学的McKendrick-Costen小组。 霍华德和埃里奥特瓦特的专业知识和仪器是互补的。 该奖项将支持Halpern教授和学生前往Heriot-Watt进行概念验证实验。 我们的目标是准备定向样品的振动激发，基态CN自由基使用模拟发射泵浦和探测的频率调制瞬态吸收光谱的准备状态。 更广泛的影响：该项目汇集了两个小组，对碰撞极化转移和淬火的研究做出了贡献。 这项合作将大大推进我们对这一基本过程的理解，这是对计算势能面并对其进行动力学研究的能力的严峻考验。 它将在大气和燃烧化学动力学等领域提供定性见解，其中小自由基能量转移和反应是基本的。 合作双方都认为这项初步工作将支持进一步的建议，出版物和学生培训。 合作的国际性推动了NSF？全球科学的目标。 霍华德大学是一所HBCU，为非洲裔美国人提供服务，并拥有大量非洲裔国际学生。 新的合作，参与霍华德学生的研究访问和机会，他们将成长出的合作，在未来将支持NSF的目标越来越多的参与，从群体在美国的STEM领域代表不足，以及有一个全球性的推广。
