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
