This award of the Professional Opportunities for Women in Research and Education (POWRE) program funded through the MPS Office of Multidisciplinary Activities (OMA) supports the research and educational activities of Professor Linda Peteanu of Carnegie-Mellon University. The research aims to extend the techniques currently existing in her laboratory to a new area, materials science, and to augment her experimental work with electronic structure calculations. Electroabsorption measurements will be made on polar polyenes using Stark-effect spectroscopy.The opportunity afforded through the POWRE program will enhance Professor Peteanu's research potential as well as her educational mentoring of undergraduate, graduate, and postdoctoral scientists. Peteanu's investigations will explore the source of discrepancies between experimentally measured and computed electronic properties for polar polyenes, which can be large if solvation effects are not adequately accounted for. The results of this research will provide a better understanding of the non-linear optical properties of polymers and glasses. This work could ultimately benefit not only manufacturing but also an understanding of the photochemistry of biological molecules in a protein environment.

通过国会议员多学科活动办公室（OMA）资助的研究和教育妇女专业机会（POWRE）的专业机会支持卡内基 - 梅隆大学的Linda Peteanu教授的研究和教育活动。 该研究旨在将目前存在的实验室中现有的技术扩展到新的领域，材料科学，并通过电子结构计算来扩大她的实验性工作。 通过鲜明效应光谱法，将对极地多烯进行电吸附测量。通过POWRE计划提供的机会将增强Peteanu教授的研究潜力以及她对本科，研究生和博士后科学家的教育指导。 Peteanu的研究将探讨极性多烯的实验测量和计算的电子特性之间的差异来源，如果不充分考虑溶剂化效应，则可能很大。 这项研究的结果将更好地了解聚合物和眼镜的非线性光学特性。 这项工作最终不仅可以使制造业有益于对蛋白质环境中生物分子光化学的理解。
