Ab initio studies of small sodium–sodium halide clusters, NanCln and NanCln−1 (n≤4)

Abstract
The geometries, energetics, and some first and second order molecular properties (dipole moments, force constants, polarizabilities) of small stoichiometric (NaCl)n and nonstoichiometric (NanCln−1), n≤4 clusters were studied at the SCF and various correlated levels.
