title: How an inert-gas matrix can modify the molecular properties of lanthanide trifluoride.
abstract: Ab initio computations performed on LaF(3) x Ar(n) (n = 1-21) complexes allow a quantification of the short-range many-body interactions arising in the argon matrix. It is shown that the molecular properties of LaF(3) are strongly influenced by the embedding medium. The largest investigated cluster, LaF(3) x Ar(21), resembles an hcp structure with the LaF(3) molecule occupying the central substitutional site (see figure).
