For example, 1,3,5-trifluorobenzene interacts with cations despite having a negligible quadrupole moment.
This quadrupole moment is associated with non-spherical charge distribution.
Working in two dimensions (x, y) the traceless or reduced quadrupole moments are.
Then the third differential of the reduced quadrupole moment where v is the velocity of material inside the source.
A quadrupole moment was found between 17 and 95 microkelvins rms, with 90% confidence level.
Atomic nuclei with spin have an electric quadrupole moment.
For this reason the nuclear electric quadrupole moment is often represented by Q.
When a nucleus has a spin quantum number, I, greater than 1/2 it has a quadrupole moment.
However, such an orbit represents a changing quadrupole moment.
You also need a quadrupole moment, so a circular orbit won't do.
