Given the Cosey, HSQC and HMBC experiments assign the
1H NMR spectrum and 13C NMR spectrum signals
of the compound. 1H peaks are labelled using lowercase
letters and 13C peaks using uppercase. Be aware that the
letters of the same peak does not necessarily refer to the position
in the molecule. For example, peak a in the 1H and peak
A in the 13C NMR are not necessarily assigned to the
same number atom. The assignment of protons 4 and...
