Dipole-dipole interactions near interfaces

The Journal of Physical Chemistry, 1993
In this paper we investigate changes in the interaction between point dipoles embedded in a liquid near a nonmetallic interface when compared to the bulk liquid. The liquid is represented in the continuum approximation, in terms of a nonlocal dielectric function t(k,w), and we analyze the dependence of the dipoledipole interactionon the distance ...

Resonant dipole-dipole interaction in a cavity

Physical Review A, 1995
Resonant dipole-dipole interaction (RDDI) in a Fabry-P\'erot cavity is studied by the mode-expansion method. It is shown that the RDDI depends upon three factors: the length of the cavity, the positions of molecules, and the polarization of dipoles.

Dipoles, dipole-dipole interactions, and spectral effects

2012
Dipoles, dipole moments, and their interactions are very important for explaining many properties of molecules that are considered in this book, including non-covalent interactions and spectra. This tutorial sets out some of the key points about dipoles and their interactions. An electric dipole...

Dipole-dipole interaction in optical cavities

Physical Review A, 1997
At the most fundamental level of quantum electrodynamics, there is no such thing as two-body interactions between atoms. The potentials that describe these interactions are effective potentials resulting from a series of approximations whose validity depends on the precise situation at hand.

Dipole–Dipole Interactions in Tungstates

The Journal of Chemical Physics, 1968
The vibrational spectra of divalent metal tungstates of the form MWO4, where M = Ba, Sr, Ca, or Zn, have been analyzed in terms of dipole–dipole interactions between adjacent tungstate ions. The van der Waals potential constants determined are of the order of (13 − 110) × 10−60 erg·cm6 and approximate those for alkali halides.

Effective dipole–dipole interactions in critical nanofluids

Journal of Magnetic Resonance, 2013
It is long known that the effective dipole-dipole coupling is averaged to zero when the spin carrying atoms are involved in a fast random movement in an unconfined fluid. The presented theory shows that if (i) the fluid is confined in long closed nanotubes, (ii) the fluid is in the vicinity of the second order phase transition, and (iii) the mobility ...

Dipole-Dipole Interaction in Simple Lattices

The Journal of Chemical Physics, 1952
A mathematical model, the spherical model, of electric dipole-dipole interaction in simple lattices is discussed. The partition function for the system, assuming just nearest neighbor interaction, is evaluated for one- and three-dimensional simple lattices. Only the three-dimensional lattice exhibits a phase transition. The transition is discussed. The

Uniaxial systems with dipole-dipole interactions

Journal of Physics A: Mathematical and General, 2000
Summary: Within the context of a model that allows for the exact calculation of the partition function, it is shown that a \(d\)-dimensional uniaxial system with dipolar interactions falls into the same universality class as a \((d+1)\)-dimensional, strictly short-range system.

Dipole–Dipole Interactions in Hydration Layer

2021
As described in Chap. 7, hydration water molecules on protein surfaces form networks of hydrogen bonds. Due to the directionality of hydrogen bonds, the orientation of hydration water molecules is restrained by polar protein atoms and adjoining hydration water molecules. In this regard, molecular dynamics simulation revealed coherent patterns of dipole

Rotational quenching of dipole-dipole interaction

Europhysics Letters (EPL), 1997
Experiments based upon light-induced drift have yielded direct information on the rotational-state dependence of intermolecular interactions. Data were obtained for the change in collision rate ν upon rovibrational (J,v) excitation of HF in Ar, H2, HCl, CH4 and CH3F. It is found that J and v have independent influences on ν. For the dipole-dipole cases,
