Determine the proton chemical shifts, integrals, coupling constants, and multiplicity for each peak in the proton NMR spectrum and add to the provided table. The table to be completed is attached. The NMR spectra is attached.
List:
Identify and highlight all cross-peaks in the COSY spectrum.
Use the HMQC and/or HSQC to identify the carbon chemical shifts of the carbon atoms with attached protons and add to the provided table.
What is the difference between the information provided between the two spectra (list at least two).
Which spectrum provides more information, and which would you prefer to use for structure elucidation of an unknown compound? Explain.
Would either of these techniques be preferred over the other for the analysis of biomolecules? Explain.
Use the HMBC spectrum to identify any additional carbon atoms in the molecule and add those chemical shifts to the provided table.
Compare the proton and carbon chemical shifts observed in the different 1-bond and multiple bond correlation spectra. Explain any chemical shift discrepancies noted between the different spectra.
Complete the table attached as screenshot for the assignment.
