With this Accomplishment Based Renewal award the Organic and Macromolecular Chemistry Program continues its support for the work of Dr. Bart E. Kahr in the Department of Chemistry at the University of Washington in Seattle. The research involves the study of the intermolecular interactions which take place during crystal growth, and will use a variety of light measurements, including absorbance, luminescence, linear dichroism, linear birefringence, and circular birefringence (optical rotation). The influences of crystals on light will be used to image actively growing crystal surfaces and measure effective electrical charges. Eventually it may be possible to provide a catalog of luminescent molecules for identifying particular crystal growth processes. Combining effects from various optical methods, including optical rotation imaging, will make it possible to learn much about these changing heterogeneous samples. Eventually it may be possible to design mixed crystals with prescribed optical properties, and to understand the role of mixed-crystal growth in the success of matrix assisted laser desorption ionization in mass spectroscopy.

有了这个成就为基础的更新奖的有机和高分子化学计划继续支持博士的工作。卡尔在西雅图的华盛顿大学化学系。 该研究涉及晶体生长过程中发生的分子间相互作用的研究，并将使用各种光测量，包括吸光度，发光，线性二色性，线性双折射和圆双折射（旋光度）。 晶体对光的影响将被用于成像活跃生长的晶体表面和测量有效电荷。 最终，可能提供一个发光分子的目录，用于识别特定的晶体生长过程。 结合各种光学方法的效果，包括旋光成像，将使人们有可能更多地了解这些变化的异质样品。 最终，它可能会设计具有规定的光学性能的混合晶体，并了解混合晶体生长的基质辅助激光解吸电离质谱的成功中的作用。
