Perturbation of the D lines of atomic sodium trapped in inert-gas matrices

Abstract

Lennard–Jones 6–12 potentials have been used with a configurational coordinate model to calculate the shift of the Na 32S → 32P transition for Na trapped in a variety of sites in solid Ar, Kr, and Xe matrices at 4°K. Multiplet structure in these systems is shown to be consistent with trapping at several distinct sites.
