- Considering the spectrum of a compound such as methanol (CH3OH).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 1H 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?
