The interaction of magnetic fields with molecular dipole moments is called the Zeeman effect.
The homogenization procedure used to obtain the macroscopic Maxwell equations from the microscopic Maxwell equations is accomplished by averaging the molecular dipole moments within a unit cell and constructing an averaged continuous charge density function.
For example, in the most commonly used theory of microelectromagnetics, materials are averaged at a molecular level to produce effective molecular dipole moments.
When an oscillating electric field of radiation interacts with the oscillating molecular dipole, an energy transfer occurs.
He and his co-workers obtained real and imaginary parts of the optical constants of the liquids for the first time and used these to derive various quantities including molecular dipole derivatives with respect to vibrational displacements.
Several attempts on postspinning modification were carried out to reduce molecular dipole interaction by modifying the precursor fibers with plasticizers, such as succinic acid, cuprous chloride, cobaltous chloride, potassium permanganate, and dimethyl formamide (10-14).
It was also argued that because surface structure, geometry, or topography played a large role in adhesion by its contribution to the defined surface field, average properties such as the dielectric constant or molecular dipole moment would never show quantitative correlations.
The anisotropy originates from the fact that molecular dipoles cannot take all possible orientations in LC phase as in isotropic phase [3].
In the fifth known crystal modification, a, the chains are packed in the unit cell in such a way that the molecular dipoles are antiparallel and there is no net (crystal) dipole [5] (Fig.
These shaped copolymers are used in drug-delivery systems, imaging materials, molecular devices, thin film devices, surface modifiers, transport agents, compatibilizers, rheology-control agents, molecular ball bearings, molecular dipoles, nonlinear optical materials, membrane and cell modifiers, complexing agents, adhesives, and interface-strengthening agents.
2~) crystallizes in space group P1 with Z = 1; thus, all molecular dipoles are in perfect alignment throughout the entire crystal lattice.
The formation of CTC results in the creation of new molecular dipoles or reorientation of the already existing dipoles.
