WebThe 1 H NMR spectrum has three singlets at δ 0.9 , δ3.45 and δ3.2 ppm; relative areas 3:2:1. Addition of D 2 O to the sample eliminates the lower field signal. The 13 C NMR spectrum shows three signals all at higher field than δ100 ppm. Which of the following compounds best fits this data? A) 1,5-pentanediol B) 1,3-dimethoxypropane WebJan 28, 2024 · The source of spin-spin coupling. The 1 H-NMR spectra that we have seen so far (of methyl acetate and para-xylene) are somewhat unusual in the sense that in both of these molecules, each set of protons generates a single NMR signal.In fact, the 1 H-NMR spectra of most organic molecules contain proton signals that are 'split' into two or more …
