Proton-bound dimer

{
  "id": "MLC-T-CHM-013449",
  "term": "Proton-bound dimer",
  "field": "Chemistry",
  "definition": "A molecular ion formed by the association of two neutral molecules with a single proton. This species is typically observed in mass spectrometry, particularly in electrospray ionization, where proton transfer reactions are common. The proton acts as a bridge between the two molecules, holding them together.",
