1 Physics A pair of equal and oppositely charged or magnetized poles separated by a distance.
- The succeeding positive slope arises due to the orientation of the headgroup dipoles.
- Interaction between the in-plane components of the headgroup dipoles is attractive and decays as the inverse sixth power of distance.
- Dielectric constants of nonpolar solvents arise from induced dipoles.
1.1 Chemistry A molecule in which a concentration of positive electric charge is separated from a concentration of negative charge.
- The relative magnitudes of the molecular dipoles can be explained by the relative electronegativity differences of the atoms forming the bonds.
- In this way, temporary dipoles are propagated through a liquid or solid.
- If there is a separation of charge in an bond, it possesses a dipole.
2An aerial consisting of a horizontal metal rod with a connecting wire at its centre.
- These methods allow engineers to fabricate many different types of planar IR antennas, including dipoles, spirals, and patches.
- One of the simplest feeds for a microwave antenna is the dipole.
- The loss of the helical spring antenna is approximately 10 dB compared to a half-wave dipole.
- Example sentences
- The spatial proximities between labels are determined by heteronuclear dipolar couplings, which are measured by rotational-echo double resonance (Gullion and Schaefer, 1989 ab).
- This expression was summed over a Gaussian distribution of dipolar couplings corresponding to a distribution of isolated 13 C- 19 F spin pairs.
- Almost certainly it involves the strongly dipolar properties of the interfacial tryptophans that are present in both the [beta] 6.3 and [arrow up] [arrow down] [beta] 7.2 structures.
