摘要
Fullerene anions with helium atoms contained inside the cage exhibit degrees of aromaticity that can be predicted through the measurement of 3He chemical shifts (see picture). These chemical shifts help to demonstrate that the magnetic properties of fullerenes, and their anions, are not simply related to the number of carbon atoms or the number of electrons in the π system.
