Abstract

The information obtainable from Stark effect measurements is examined with particular reference to naphthalene-type host crystals. Consideration of the angular dependence of the splitting suggests that its experimental study could provide improved data and test theoretical analyses. It is shown that the derived dipole moment change Δμ depends on the polarizability change Δa, being perhaps 15% greater for Δa = 0 than for a plausible nonzero Δa. Neglecting Δa, Stark measurements for one guest in three host crystals would yield Δμ and the unknown internal field components not fixed by crystal structure and susceptibility. Such measurements could also yield an estimate of Δa and an improved Δμ.
