Quadrupolar nuclide

{
  "id": "MLC-T-CHM-009723",
  "term": "Quadrupolar nuclide",
  "field": "Chemistry",
  "definition": "An atomic nucleus that possesses a nuclear electric quadrupole moment, meaning its charge distribution is not perfectly spherical. This occurs for nuclei with a spin quantum number (I) greater than 1/2. Such nuclides interact with electric field gradients in their molecular environment, leading to quadrupolar coupling, which affects their nuclear magnetic resonance spectra.",
