摘要
2D—NMR是近十年来出现的新技术,在有机分子结构的研究中起着重要作用.本文是用同核、异核化学位移相关二维谱、异核中继根干传递二维谱和异核远程偶合相关二维谱,对四个新的5—氟脲嘧啶衍生物进行了全面的研究,确定了它们的结构及~1H、^(13)C谱线归属.
2D-heteronuclear relayed coherence transfer and 2D-long range heteronuclear correlation spectroscopy were successfully applied to the determination of the structures and the assignment of resonances of 5 -fluorouracil derivatives. The results show that XCORFE method plays an important role in confirming the connection mode of quaternary carbon or other atoms in the molecules.
