Buckminsterfullerene is a conjugated electron‐accepting molecule that has potential use in nonlinear optical applications, while the addition of endohedral lithium should transfer charge to the carbon cage, ultimately providing a low potential energy surface for the motion of the Li atom. These authors present a theoretical and experimental investigation into the second hyperpolarizability of Li@C 60 , and show that the presence of a Li atom inside a C 60 cage increases its second hyperpolarizability by an order of magnitude.
