The Department of Chemistry is developing a project based on its acquisition of a single crystal x-ray diffractometer. Single crystal diffractometry has become the standard method for the characterization of crystalline materials and should be taught in the undergraduate curriculum. Recent improvements in instrumentation, including speed of data collection and significant reductions in price, make this feasible. In addition to the benefits of training in modern instrumental methods, there is a decided benefit to chemistry students through the enhancement of spatial reasoning skills from continued exposure to three-dimensional problems and three-dimensional images that can be manipulated by computer. The department plans to introduce the instrument in a limited fashion in the freshman year and, with increasing sophistication, each subsequent year, culminating with a project in which students mount a crystal, collect data, assign a space group, and determine the structure during the senior year.

化学系正在开发一个基于其获得的单晶X射线衍射仪的项目。单晶衍射法已成为表征晶体材料的标准方法，应在本科课程中教授。最近仪器的改进，包括数据收集速度和价格的大幅降低，使这一点成为可能。除了在现代仪器方法的培训的好处，有一个决定性的好处，化学学生通过空间推理能力的提高，从持续接触三维问题和三维图像，可以通过计算机操作。 该部门计划在大一以有限的方式引入该仪器，并在随后的每一年中不断增加复杂性，最终以学生安装晶体，收集数据，分配空间组并在大四期间确定结构的项目而告终。
