Proton NMR Tetracyclone
« on: August 25, 2013, 10:30:30 AM »
The big question is: Why Proton NMR is not a useful way to characterize tetracyclone? When the synthesis of tetracyclone is done, only the IR spectrum is taken. Proton NMR could also be taken but why is it not useful for the identification of tetracyclone? Is it because the number of signals the NMR spectrum produced is not enough for the full identification of the compound? Not sure... Help greatly appreciated.

HNMR Spectrum of tetracyclone:

If you check H's of the compound ,then they all are aromatic and will not give you very distinct signals because of the nearly same chemical environment.
