Professor Anne Kelley of Kansas State University is supported by the Experimental Physical Chemistry Program to perform advanced spectroscopic studies of molecules with potential for good nonlinear optical responses. By quantitatively simulating the absolute resonance Raman intensities and optical spectra of these species in solution, the PI will experimentally determine the effect of solvent environment on the structures of both the ground and lowest excited electronic states of the molecules. Neural networks will be tried for fitting experimental data to models. The molecules will also be studied embedded in polymer matrices at 5K using single molecule emission spectroscopy. It is important to be able to quantify the relation of optical and nonlinear optical responses to solvent effects, if these molecular structures are to be incorporated into polymer matrices to fabricate devices. This work will improve our ability to convert sophisticated spectral data into predictive models for new optical materials. Optical materials are needed for advances in optical computing and communications.

堪萨斯州立大学的Anne Kelley教授得到实验物理化学计划的支持，对具有良好非线性光学响应潜力的分子进行高级光谱研究。 通过定量模拟溶液中这些物质的绝对共振拉曼强度和光谱，PI将通过实验确定溶剂环境对分子基态和最低激发电子态结构的影响。 将尝试用神经网络将实验数据拟合到模型中。 还将使用单分子发射光谱法在5K下研究嵌入聚合物基质中的分子。重要的是能够量化的光学和非线性光学响应的溶剂效应的关系，如果这些分子结构被纳入聚合物矩阵制造设备。 这项工作将提高我们将复杂的光谱数据转化为新光学材料预测模型的能力。 光学计算和通信的发展需要光学材料。
