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

The influence of a.c. electric field (5kHz) on the IR and FIR spectra of the nematic phase of some liquid crystals with strong positive dielectric anisotropy ( Eaz 10 -20) and weak negative dielectric anisotropy (6,~ -0,2 -0,7) was investigated. The changes in the half-widths and integral intensity
