异丙醇(67-63-0)核磁图(HNMR) in CD3OD 90 MHz in CDCl3 in CD3CN in DMSO-d6 in CDCl3
在MestReNova完成1H NMR图谱整个峰化学位移对齐以及分段积分之后,整个1H NMR图谱被细分为多个区域,每个区域所有点的积分值累加起来可以抽象的代表整个原始图谱[36],这些代表性的区域积分值作为接下来建模的输入变量,从而实现对每1H NMR图谱约60 000个高共线性数据点的有效降维。 选取了0.01, 0.015, 0.02, 0.025, 0.03...
四氢呋喃(109-99-9)核磁图(HNMR) in DMSO-d6 in CD3OD in CDCl3 in CD3CN 90 MHz in CDCl3
The spectrum of the bismuth complex, Bi(S2COEt)3 exhibits five resonances in the ratio 1:1:2:1:1. The data have been interpreted as being consistent with the presence of two polymorphs of the complex (see later, Fig. 7) [112]. Table 1. 1H- and 13C-NMR resonance for the methylr...

1H NMR Spectrum 13C NMR Spectrum 试推测其化学布局.相关知识点: 试题来源: 解析 答:计算出不饱和度为1.2应该是亚甲基,两个3应该是甲基.甲基裂坡成了三重坡,亚甲基裂坡成了四重坡,说明这边刚好是个乙基.在210左右有个吸收峰,这是典型的羰基的一个吸收峰.40左右有个碳的信号,应该是受到了氧的诱导效应的...
