13C NMR Signal and Chemical Shift tural abundance of the ich is 99.985% of hydrogen Sassi The isotope 18C is another NMR active nucleus. The natural abundance isotope is only 1.1% of carbon atoms compared to the 'H isotope which is 99.985% of atoms. Therefore the intensity of WC peaks is lower. It takes a longer time to obtain a spectrum compared to a 'H NMR spectrum. Adjacent WC - WC splitting does occur. chance of two "C atoms being...

Draw the expected H NMR spectrum for each molecule. Pay
attention to the chemical shift and splitting. Mark the integration
of each peak. Then assign each peak in the NMR to hydrogen atoms in
the structure.
