In this project, funded by the Experimental Physical Chemistry Program of the Chemistry Division, Prof. Roger E. Miller of the University of North Carolina - Chapel Hill will conduct experiments with his undergraduate, graduate and post-doctoral research students to study a wide variety of chemical systems confined to cold helium droplets. The nature of the cold droplets allows Miller and his group to study a wide range of chemically interesting systems that would be difficult or impossible to study by other means. Included in these studies will be continued studies of hydrogen-bonded systems, highly reactive radical molecule complexes, metal and semiconductor clusters, and small biomolecules. Additional experiments will be performed with a powerful infrared pump laser to investigate intramoleuclar rearrangements and bimolecular reactions. The results from these very basic studies will be applicable to a wide variety of disciplines from nanoscience to biophysics. Besides the broader impact of the research that will be performed, students trained in the Miller group are given a very broad training across many scientific disciplines.

在该项目中，北卡罗莱纳大学教堂山分校的Roger E. Miller教授将与他的本科生、研究生和博士后一起进行实验，研究各种局限于冷氦液滴的化学系统。冷液滴的性质使米勒和他的团队能够研究各种化学上有趣的系统，这些系统很难或不可能通过其他方法进行研究。包括在这些研究将继续研究氢键系统，高活性自由基分子络合物，金属和半导体团簇，以及小生物分子。另外的实验将使用强大的红外泵浦激光器来研究分子内重排和双分子反应。这些非常基础的研究结果将适用于从纳米科学到生物物理学的各种学科。除了将进行的研究产生更广泛的影响外，在米勒小组接受培训的学生还接受了许多科学学科的广泛培训。
