PE01 NMR studies on rod-like molecules in solvent

Abstract

In order to study the pre-transitional behavior of solid-mesophase and/or isotropic-mesophase transitions, the molecular dynamics of rod-like molecules in a solvent is investigated by means of ^<13>C-NMR. Concentration dependences of chemical shift, half-width of peak and spin-lattice relaxation time T_1 are estimated. With appearance of the crystalline solid in the solution, the correlation time τ_c corresponding to the T_1 becomes longer.
