Another alternative, proposed by Pan, Fang and Chai,^{725} is to
use a *localized* version of Fermi-Amaldi exchange-correlation functional.
The resulting exchange density functional, whose functional derivative has the
correct $-1/r$ asymptotic behavior, can be directly added to any semi-local
density functional. Three variants of this method were proposed in
Ref. 725. The simplest of these, the strictly-localized
Fermi-Amaldi (LFAs) scheme, is implemented in Q-Chem, for molecules
consisting of atoms with $Z\le 55$.
