The undergraduate chemistry program at Bucknell University will be enhanced significantly by providing students with laboratory experience in crystallography. This project will install an X-ray generator and a precession camera with Cu and Mo sources. The precession camera will be used at all levels of undergraduate instruction for projects not previously possible. In general chemistry, a library of precession photographs and exercises will be generated to enable students to visualize the reciprocal lattice and crystal symmetry elements. In physical chemistry laboratory, undergraduates will obtain their own precession photographs and assign space groups. In undergraduate research, students will derive unit cell parameters and assign space groups for their own syntheses, preparatory to full single crystal structural determinations.

通过为学生提供结晶学的实验室经验，巴克内尔大学的本科生化学课程将得到显著加强。该项目将安装一台X射线发生器和一台带有铜和钼源的进动相机。进动相机将用于所有级别的本科教学，用于以前不可能完成的项目。在普通化学中，将生成一个进动照片和练习库，使学生能够可视化倒易晶格和晶体对称元素。在物理化学实验室，本科生将获得他们自己的进动照片并分配空间群。在本科生的研究中，学生将得到晶胞参数，并为他们自己的合成指定空间群，为完全单晶结构确定做准备。
