need help drawing the structures for each
For each pair of spectra, first calculate the THD for the molecular formula. Then draw a structure which matches all features of both spectra (there may be more than one structure which fits). For partial credit, write out individual spectral interpretations on each spectrum, noting either presence (or absence) of FG's or bond types. Remember your calculated IHD!! (6 points each) 1.
