  "id": "MLC-T-CHM-003225",
  "term": "Dimeric ion",
  "field": "Chemistry",
  "definition": "An ion made of two molecular units, formed either when a species that exists as a dimer in the vapor is ionized and detected intact, or when a molecular ion attaches to a neutral molecule of the same kind in the ion source, giving a radical cation such as M2+. Proton-bound dimers, written (2M + H)+, are common examples in chemical ionization and electrospray mass spectra.",
