9.11: Structure Determination (Problems)

  • P9.1:

    1. For each molecule below, draw in all hydrogen atoms, and label them \(H_a\), \(H_b\), etc., with chemically equivalent hydrogens having the same label.
    2. Predict splitting patterns for all proton signals.



    P9.2: For each of the 20 common amino acids, predict the number of signals in the proton-decoupled \(^{13}C-NMR\) spectrum.

    P9.3: Match spectra below to their corresponding structures A-F. Make complete peak assignments for all structures.

    (in all \(^1H-NMR\) data tables in the following problems, peak relative integration values are listed in which the smallest area peak is equal to 1)
