资源简介:
Carbon-13 (C13) nuclear magnetic resonance (most commonly known as carbon-13 NMR spectroscopy or 13C NMR spectroscopy or sometimes simply referred to as carbon NMR) is the application of nuclear magnetic resonance (NMR) spectroscopy to carbon. It is analogous to proton NMR (1
H
NMR) and allows the identification of carbon atoms in an organic molecule just as proton NMR identifies hydrogen atoms. 13C NMR detects only the 13
C
isotope. The main carbon isotope, 12
C
is not detected. Although much less sensitive than 1H NMR spectroscopy, 13C NMR spectroscopy is widely used for characterizing organic and organometallic compound
碳-13核磁共振(通常称为碳-13核磁共振波谱或13C NMR波谱,有时亦简称为碳NMR)是将核磁共振波谱技术应用于碳元素的一种方法。其原理与质子核磁共振(1H NMR)相似,能够实现对有机分子中碳原子的识别,正如质子核磁共振对氢原子的识别。13C NMR仅检测13C同位素。主要的碳同位素12C则不被检测。尽管其灵敏度远低于1H NMR波谱,但13C NMR波谱在有机及有机金属化合物的表征中仍得到了广泛的应用。
