ORAL CONTRIBUTION

Hyperfine interactions can be a powerful tool to identify local environments in many different systems. Recently it has been drawn attention to the possible application of the Time Differential Perturbed Angular Correlation (TDPAC) technique to study differences in the Nuclear Quadrupole Coupling constants ( υQ ) at Cd probes in mouse DNA infected with the Trypanosoma Cruzi. The electric...

20. Proton Dynamics in One-dimensional Hydrogen-bonding System in Molecular Co-crystals TMP-D2ca and DMP-H2ca

ORAL CONTRIBUTION

Recently, hydrogen-bonded supramolecular co-crystals have attracted much interest in aim for functional materials such as ferroelectrics [1]. By use of 35Cl nuclear quadrupole resonance (NQR) we have studied an organic ferroelectric, phenazine(Phz)-chloranilic acid (H2ca) co-crystal, Phz-H2ca, and found an electric field gradient fluctuation probably due to a proton dynamics in hydrogen bond...
