# 13C-NMR of aniline: Why are carbons that are further from the amine group more downfield than carbons that are closer? [closed]

A $$\ce{^{13}C}$$-NMR of aniline shows that the carbons further from the $$\ce{-NH2}$$ group are more downfield than the ones near the top of the benzene ring. If electronegative atoms like nitrogen have a deshielding effect on nearby Carbons, why is this the case? Is it because of dipole vectors?

• I strongly suggest using deshielded/shielded instead of downfield/upfield, as the latter terms are historical relics from an old way of doing NMR (continuous wave). Deshielded/shielded is really more intuitive and easily relatable to other chemistry concepts. – orthocresol Oct 1 '20 at 9:39
