dipole-dipole interaction energyData for Δ H τ, the enthalpy of activation determining the temperature dependence of the Debye relaxation time have been collected and compared for polar aprotic solvents of lower molecular weight. It is shown that the variation in this quantity with solvent can be...
Here we use a molecularstatistical theory to show that sufficiently strong polar interactions between bent-shaped molecules may lead to experimentally observed reduction of the bend elastic constant in the nematic phase even if electrostatic dipoledipole interactions are not taken into account. We ...
By focusing on repulsive interactions between interstitials, we reveal that the long-range tail of the dipole-dipole interaction have the role of increasing the energy cost of domain wall formations. This effect produces the supersolid by the second-order hopping process of defects. We also perform...
These interactions, termed “weakly polar,” result from the characteristic distribution of partial charges in some amino acid side chain moieties and involve interactions among electronic monopole, dipole, and quadrupole moments.Access through your organization Check access to the full text by signing ...
where the spin is represented by a single-valence electron of a heteronuclear molecule. The combination of microwave excitation with dipole–dipole interactions and spin–rotation couplings enables building a complete toolbox for effective two-spin interactions with designable range, spatial anisotropy and...
The polar part is that part of the surface free energy of a solid or the surface tension of a liquid which is due to polar interactions. When the polar part and the disperse part of the surface tension of liquids are known, the surface free energy of a s
and the association of mesogens due to dipole-dipole forces can be studied. The measurements suggest that at very low concentrations the dipole-dipole interactions result in a small increase in the effective dipole moment. while at higher concentrations local antiferroelectric order becomes dominant. ...
Long-range dipole-dipole interactions between polar molecules in an optical lattice enable rotational excitations to move through the lattice even when the molecules themselves cannot, as has been directly observed in recent experiments [Yan et al., Nature 501, 521-525 (2013)]. We study the dyna...
