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...
