Some proton environments that are identical in the conventional analysis of NMR have different chemical shifts, such as by being close an electronegative atom. What is an example of a theoretical calculation that can be carried out to produce NMR spectra that gives results which are closer to the actual data attained from the experiment?

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...
