Anionized molecule

  "id": "MLC-T-CHM-000616",
  "term": "Anionized molecule",
  "field": "Chemistry",
  "definition": "An ion produced when an anion attaches to a neutral molecule M, for example the chloride or formate adduct of M seen in negative-ion mass spectrometry. It differs from a deprotonated molecule, which forms by losing a proton, and from a radical anion, which forms by capturing an electron. For a singly charged adduct the mass-to-charge ratio equals the mass of M plus the mass of the attached anion.",
