Heat capacities of a molecular mixed-ligand complex [Zn(hfac)2(tmen)] were measured in the temperature range between 13 and 383 K with an adiabatic calorimeter and the proton magnetic spin–lattice relaxation times (T1, T1ρ and T1D) were measured i

EPR has been observed in a single crystal of [P(C6H5)4][CuCl3] at room temperature. The spectrum was characteristic of a spin one system, indicating that the copper(II) ions are pairwise coupled in the crystal. The present results agree fairly well w

The NQR frequency and the spin - lattice and spin - spin relaxation times were measured as functions of temperature, in order to study the structural phase transitions in deuterated ammonium hexachloroplumbate(IV) . It was shown that the phase transi

K2SeCl6 undergoes structural phase transitions of first order at 35 K, 65 K, and 79 K. The temperature dependence of the 35Cl NQR spin-lattice relaxation time suggests that the phase transitions at 65 K and 79 K are displacive ones associated with a

Seven new derivatives of 4-octyloxy-N-(4-substituted benzylidene) aniline have been synthesized. 4-Trifluoromethyl and 4-trifluoromethoxy derivatives exhibit stable smectic B and A phases, respectively, while both the 4-methyl and 4-methoxy derivativ

An anionic motion in sodium thiocyanate was studied by the spin-lattice relaxation time measurements of 14 N nuclear quadrupole resonance. The relaxation time decreased rapidly obeying an Arrhenius equation above T = 375 K. This result suggests the o

The nature of the smectic Ad to nematic phase transition and the modes of molecular motion were investigated for the homologous mesogens, CBOOA, NBOOA, and their chain-deuteriated compounds. In NBOOA, the SA d[sbnd]N phase transition was found to be
