13C NMR分子式：分子量：CAS号：性质：在恒定磁场中碳13原子核受射频辐射照射，当射频频率相当于核能级间隔时，产生共振吸收谱的方法。碳是有机分子量基本的成分，因此13C NMR 能提供有关分子骨架的信息。13C NMR 谱比较简单，容易解析，但信号强度较弱，灵敏度低。采用脉冲傅里叶变换技术（PFT）是13C NMR 实验技术的一次重大突破该技术采用时间短、功率大的射频辐射脉冲（1微秒达1千瓦）照射样品，脉冲包含各种频率，它破坏核能级的平衡集居数，当辐射脉冲停止后，体系趋向恢复平衡态而放出能量，记录不同时间的信号，用计算机傅里叶变换技术将时间函数变换为频率函数，将多次相继的脉冲的结果累加在一起，便得到13C NMR谱。该法快速而灵敏度高，在结构分析、分子生物学研究等领域中是一种很有用的新技术。
