The liquid crystal orientation technique has been utiiized to determine the j#arizatfon of the emission from complexes formed in the excited state. The experimentaL results agree wtth theoretfcal predicttons made for hetero-excimers with appreciable admixture of locally excited states.

β¦ Synopsis
Fluorescence polarization experiments on molecules dissolved in ordered liquid crys+als are described. It has been found that the monomer and excimer emissions of pyrene are perpenciicuLarLy polarized.

It has been demonstrated that the natural abundance 2 H NMR spectra of molecules dissolved in liquid crystals can be obtained easily with the help of present-day high-resolution FT NMR spectrometers. Such spectra obtained in the case of benzene and chloroform dissolved in liquid crystals are reporte
A current modal. which forms the basis for the molecular field treatments of the orientationat ordering of molecules in liquid crystals, is examined using a cluster variation method. It is found that no firstorder transition occurs.
