11. For example, the " quadrupole moment " is the basis for the next term: 12. Since a deuteron is composed of a proton and a neutron with aligned spins, the electric quadrupole moment . 13. Being a 3-dimensional rank-2 tensor, the quadrupole moment has 3 2 = 9 components. 14. While benzene does not have a dipole moment, it has a strong Quadrupole moments of benzene and hexafluorobenzene. 15. For this reason the nuclear electric quadrupole moment is often represented by " Q " " zz ". 16. It is mainly a magnetic dipole moment; the quadrupole moment does cause some small shifts in the hyperfine structure as well. 17. Monopole moments have a rate of decrease, dipole moments have a rate, quadrupole moments have a rate, and so on. 18. The refinement and evolution of the Rabi measurements led to the discovery in 1939 that the deuteron also possessed an electric quadrupole moment . 19. Each chlorine molecule carries permanent multipole moments of even order, the first one being a permanent quadrupole moment ( order 2 ). 20. This indicates that the quadrupole moment can be quantized in order of the Mathieu characteristic values a _ n and b _ n.
