Simplified view of a negatively charged solid spherical particle surrounded by electrically neutral polarized water molecules (1 is a solid particle, 2 is a molecular dipole
of water, and 3 is an electron)
That is, the vector of the molecular dipole
is given by [delta].r, being [delta] partial atomic charge and r the bond distance (Figure 1).
of the molecular dipole
and final heat of formation are quantum chemical descriptors.
The molecular dipole
moment is perhaps the simplest experimental measure of charge distribution in a molecule.
The interaction of magnetic fields with molecular dipole
moments is called the Zeeman effect.
IR peaks result from an absorption of energy caused by molecular dipole
moment vibrations and are plotted as intensity versus frequency in wavenumbers ([cm.sup.-1]).
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 .
