Sentences with phrase «electric dipole»

This long - range force among atoms or molecules arises from the temporary appearance of electric dipole moments in the particles.

Overtones for H2O and CO2 are allowed for electric dipole transitions because of small anharmonicities in the vibrational potential energy but are as it says, really weak.

N2 and O2 vibrational transitions period are forbidden by symmetry for electric dipole transitions.

The mechanism of the subsequently applied relatively new cooling technique relies on the fact that these molecules exhibit a permanent electric dipole moment (i.e. the negative charge is shifted towards the oxygen atom).

The van der Waals force is the attractive sum of short - range electric dipole interactions between uncharged molecules.

«This is the largest electric dipole moment ever observed in a molecule,» says James Shaffer, professor in the Homer L. Dodge Department of Physics and Astronomy, OU College of Arts and Sciences.

The absence of radiation is the result of the current being divided between two different components, a conventional electric dipole and a toroidal dipole (associated with poloidal current configuration), which produce identical fields at a distance.

Such currents arise from each object's fluctuating electric dipoles, or, its distribution of negative and positive charges.

Each magnetic monopole comes with an electric dipole, but for most materials the electric polarization is so small that it can not be seen.

The electron's egg shape, if real, would be quantified by what is known as the electric dipole moment (EDM).

Even for a neutral atom, a momentary imbalance of charge — more of the atomic electrons» negative charge might appear to the left, say, leaving a positive preponderance on the right — will constitute an electric dipole, which in turn can attract an atom with a complementary dipole orientation.

When the field interacts with an atom, it alters the distribution of electrons around the atom, thereby inducing an electric dipole moment.

Physicists call this kind of arrangement an electric dipole.

The measurements also will help direct the searches for atomic EDMs (electric dipole moments) currently being carried out in North America and Europe, where new techniques are being developed to exploit the special properties of radon and radium isotopes.

By doing so, you also create an electric dipole.»

«These electric dipoles interact with each other over fairly large distances, a good fraction of a micron, or 1,000 nanometres.

Three efforts to achieve such measurements are behind schedule, but if an electric dipole moment is confirmed in neutrons, it would violate the standard model of particle physics

In theory, this arrangement could create an electric dipole moment (EDM)-- an offset between the centres of positive and negative charge.
