When MHPOBC leaves the solution and deposits as crystals, peak broadening, which may result from a slowing down of molecular motion, occurs simultaneously. In addition, the correlation time τc of the corresponding molecular motion is estimated to be approximately 10−8 s by the spin-lattice...
NMRslowing downspin-lattice relaxationTo investigate the molecular dynamics of rod-like molecules in solution, 13C-NMR measurements of a liquid crystalline material (4-(1-methylheptyloxycarbonyl)phenyl 4′-octyloxybiphenyl-4-carboxylate: MHPOBC) with a CDCl3 solvent are carried out. When MHPOBC ...
