核磁共振是一門用途極為廣泛的光譜學,到目前為止,因核磁共振而得諾貝爾獎的學者已達六位之多。核磁共振目前有三大分支,分別為液態核磁共振、固態核磁共振及磁共振成像。本文將集中討論固態核磁共振的一些原理及應用,內容包括多二級結構之測量,玻璃系統的結構鑑定,及生物礦化的研究。
Nuclear magnetic resonance (NMR) spectroscopy has a large variety of applications. To date, six scholars have been granted the Nobel prizes because of their NMR based research. There are three sub-disciplines in NMR spectroscopy, viz. the solution-state NMR, solid-state NMR and magnetic resonance imaging. In this short review article, we will briefly discuss some of the common techniques of solid-state NMR and their related applications, including the determination of backbone torsion angle of polypeptides, the structural elucidation of glass systems, and the study of biomineralization.
