We will find the static magnetic field as [h.sub.1], [h.sub.2] and d [right arrow] 0 and I [right arrow] [infinity] such that the partial

dipole moments [m.sub.1] = [S.sub.1]I and [m.sub.2] = [S.sub.2]I remain finite.

The DC discharge nozzle was employed in the study of radicals or transient interstellar species to measure low-J rotational transitions and to determine the

dipole moments (138), (139).

Spotting the

dipole moment would mean that the electron has some kind of internal structure, a bizarre concept for a particle that is supposed to buzz around the nuclear hearts of atoms and molecules with its mass concentrated into an essentially sizeless point.

DFT method with Gaussian 09 program with the B3LYP functional and 6-31G(d,p) basis set was used for calculation of physical properties of compounds including stability, Gibbs free energy,

dipole moment in different solvents such as EtOH, MeOH and H2O [15].

Due to the important application of

dipole moment in the research of polarizability and the first hyperpolarizability, the [mu] of Tetrabromophenol blue and Bromoxylenol blue is calculated to be 3.9514 D and 9.0229 D, respectively, and [[mu].sub.x] is the

dipole moment component perpendicular to the direction Ti[O.sub.2] surface, and they are 1.3838 D and 0.6012 D, respectively.

In spite of this system being nonlocal, that is, the field at any point depends on the field at two centers of spheres, it is rather easy to obtain the expression for the

dipole moment of any sphere:

When the two

dipole moments are equal, Equation 2 is simplified:

Heckel, "Reduced limit on the permanent electric

dipole moment of [sup.199]Hg," Physical Review Letters, vol.

When Re {f([[epsilon].sup.*.sub.p], [[epsilon].sup.*.sub.m])} > 0 the effective

dipole moment is aligned with the electric field E.

The scattered fields are calculated by using the DM approach described in Section 3.2 but with the

dipole moments Ils calculated using the complex permittivity in the consistency condition (5) and compared with those generated using a commercial FEM code.

The main reason for the change of surface feature is the break of atoms bonds in the outmost surface layer, there are uncompensated electrons, and

dipole moment directing to outside is formed.
