= Nuclear quadrupole resonance
{wiki=Nuclear_quadrupole_resonance}
Nuclear quadrupole resonance (NQR) is a spectroscopic technique that exploits the interaction between nuclear quadrupole moments and an electric field gradient in a sample. Unlike nuclear magnetic resonance (NMR), which requires an external magnetic field and is sensitive to the magnetic moments of nuclei, NQR is fundamentally based on differences in the electric field experienced by nuclei with a non-spherical distribution of charge (quadrupole nuclei).
