β环糊精(β-cyclodextrin)的核磁共振谱(NMR spectrum)主要包括以下峰: 1. H-1谱峰:β环糊精中含有7个氢原子(H-1至H-7),这些氢原子产生了一组峰。在H-1谱峰中,可以观察到7个峰,峰的化学位移(chemical shift)通常在δ 4-6之间。 2. H-3和H-5谱峰:β环糊精中的H-3和H-5氢原子在H-1谱峰的附...

2024/2/12⑵碳—13核磁共振谱(13C-NMRspectrum,13CNMR),简称碳谱。碳谱弥补了氢谱的不足,可给出丰富的碳骨架信息。特别对于含碳较多的有机物,具有很好的鉴定意义。缺点峰面积与碳数一般不成比例关系,因而氢谱和碳谱可互为补充。⑶氟与磷核磁共振用于鉴定,研究含氟及含磷化合物,用途远不如氢谱及碳谱广泛。氮...
