Abstract

Nuclear magnetic resonance (NMR) spectroscopy has provided a unique opportunity to study the characteristic smectic-A to chiral nematic phase transition in a dimesogenic liquid crystal ("KI-5S"). The order parameters in the liquid crystalline phases were obtained from the <sup>2</sup>H NMR quadrupole splitting and <sup>13</sup>C NMR chemical shift measurements, manifesting a first-order smectic-nematic phase transition.
