A nuclear electric quadrupole moment describes the effective shape of the ellipsoid of nuclear charge distribution. The quadrupole moment depends upon the size and charge of the nucleus.
EQ=+or -[(2J-1)/2(J+1)]*(3/5*R*R) Where EQ --> Electric Quadrupole moment J-->Total spin of the Single unpaired Eletron R-->Radius of the Nucleus
Yes, yes, go on. What is your question ?
when dipole moment,torque and electric field all the three are perpendicular to each other.
direction-along the axis of dipole from -q to +q.
In NMR, nuclei with spin ≥ 1/2 have a magnetic dipole moment so that their energies are split by a magnetic field, allowing resonance absorption of energy related to the difference between the ground state energy and the excited state. In NQR, on the other hand, nuclei with spin ≥ 1 , such as 14N, 35Cl and 63Cu, also have an electric quadrupole moment so that their energies are split by an electric field gradient, created by the electronic bonds in the local environment. Since unlike NMR, NQR is done in an environment without a static (or DC) magnetic field, it is sometimes called "zero field NMR". Many NQR transition frequencies depend strongly upon temperature. Any nucleus with more than one unpaired nuclear particle (protons or neutrons) will have a charge distribution which results in an electric quadrupole moment. Allowed nuclear energy levels are shifted unequally due to the interaction of the nuclear charge with an electric field gradient supplied by the non-uniform distribution electron density (e.g. from bonding electrons) and/or surrounding ions. The NQR effect results when transitions are induced between these nuclear levels by an externally applied radio frequency (RF) magnetic field. The technique is very sensitive to the nature and symmetry of the bonding around the nucleus. The energy level shifts are much larger than the chemical shifts measured in NMR. Due to symmetry, the shifts become averaged to zero in the liquid phase, so NQR spectra can only be measured for solids.

Zero Dipole would set itself such that dipole moment vector is along the electric field vector
when dipole moment,torque and electric field all the three are perpendicular to each other.
Q1:How to calculate electric potential due to a dipole? Q2:How to calculate electric potential due to ring of charges? Q3:How to calculate electric potential due to charge disk? Q4:how to calculate electric potential due to a quadrupole?
See the Web Links to the left for the answer.
There is a dipole moment on acetic acid. The O-H bond in acetic acid is highly polar, as is the double C=O bond. The arrangement is not symmetrical, so the dipoles do not cancel one another out.
Magnetic dipole is due to two poles of magnet. Electric dipole is due to +ve and -ve charges of electric charges.

magnetic quadrupole is actually a group of four magnets with one pole of each adjacent magnets attract each other such that they create a Magnetic_fieldwhose magnitude Linear_functionwith the Radiusdistance from its longitudinal Coordinate_axis. This is used in Particle_beamfocusing.
