X-ray microsource upgrade for accessing very small and/or organic single crystal structures

单晶X射线衍射，它提供了分子固态结构的“球和棒”图片，可能是无机化学家最关键的表征工具，对有机化学家也非常有价值，特别是在确认原子连接性和相对（或绝对）立体化学方面。虽然SFU化学系有一个现代化的单晶X射线衍射仪，它只配备了一个基于氘的X射线源，这是不适合对小和/或有机晶体进行测量。 因此，该提案旨在为SFU单晶X射线衍射仪的关键升级提供资金：增加高强度铜基微焦点X射线源。 这一升级将极大地影响大多数有机和无机化学的研究计划。SFU的研究人员打开了从小的弱衍射晶体和有机晶体中获得高质量结构数据的大门。

Single-crystal X-ray diffraction, which literally provides a "ball-and-stick" picture of the solid-state structure of molecules, is perhaps the most critical characterization tool for inorganic chemists and is also very valuable for organic chemists, particularly for confirming atomic connectivity and relative (or absolute) stereochemistry. Although the SFU Chemistry Department has a modern single-crystal X-ray diffractometer, it is only equipped with a molybdenum-based X-ray source, which is not appropriate for making measurements on small and/or organic crystals. Thus, this proposal seeks funding for a critical upgrade to SFU's single-crystal X-ray diffractometer: the addition of a high-intensity copper-based microfocus X-ray source. This upgrade will greatly impact the research programs of most organic and inorganic chem. researchers at SFU by opening the door to obtaining high-quality structural data from small, weakly diffracting crystals and organic crystals.
