Considering the spectrum of a compound such as methanol (CH 3 OH).Using the rules for coupling we have established, predict the number of resonances and identify their multiplet structure. However, in other situations the spectrum of methanol appears as two singlets, one of area three and the other of area one.Propose a reason why singlets are observed instead of coupled multiplets. Another time-dependent aspect to consider about NMR spectra can be illustrated by considering the 1 H NMR spectrum of N , N -dimethylacetamide (DMA) shown below. What does the NMR spectrum of DMA look like? DMA has the following contributing resonance form.What would the NMR spectrum of DMA look like in this resonance form?
