13C 磁共振谱  13C(核自旋量子数I为1/2)在静磁场中能级分裂和从射频电磁波吸收能量由低能级跃迁至高能级而产生的磁共振谱,与质子磁共振谱相似,但有以下差别:①它在高能级的寿命较长,限制了使之进行跃迁的射频电磁波的功率;②磁共振的灵敏度与旋磁比γ 的三次方成正比,而,致使13C磁共振是1H磁共振的灵敏度的1/64;③13C的天然同位素丰度为1.1%,而1H则为99.8%,所以它的灵敏度又要比1H磁共振低两个数量级;④13C磁共振谱的分辨能力高,其化学位移范围为600微克(1H磁共振的仅为20微克),从而对分子量为300~500的有机化合物几乎可分辨每一个13C峰,这在1H磁共振中决不可能。从13C磁共振可以观测不与质子相连的基团,如C=O、C呏N等基团。
