This research, part of the Physical Chemistry Experimental                      Program, will use carbon-13 NMR to study orientational ordering                 of liquid crystals.  The method to be used involves the removal                 of proton-proton couplings, rapid sample spinning near the                      magic angle and reduction of carbon-proton couplings, coupled                   with the use of Fourier transform techniques to resolve peaks                   of different carbon atoms.  Several systems will be studied by                  this method including nematic liquid crystals in the mesogenic                  core.  The effects of substituents in the side chain of                         ferroelectric liquid crystals will be correlated with their                     spontaneous polarization.  Orientational ordering of side chain                 liquid crystal polymers with polyacrylate and polysiloxane                      backbones will be investigated.  Chain ordering calculations                    based upon molecular field theory will be performed to analyze                  the experimental results.
