โœฆ Synopsis

A rigorous treatment of the local electric field is used to calculate effective molecular polarizabilitics from optical data for naphthalenc, anthracene, phenanthrene and biphenyl crystals. The principal axes of polarizability are typi-c~lly 10" from the molecular axes, in accord with spectroscopic results. Various appliations are outlined.

The general solution for the effective polarizability in naphthalene-type crystals depends on two arbitrary parameters. These are eliminated by fixing one principal axis of polarizability parallel to a molecuiu -,k; numcricd results are given for naphthalene.
