Protonated molecule

{
  "id": "MLC-T-CHM-013448",
  "term": "Protonated molecule",
  "field": "Chemistry",
  "definition": "A molecule that has gained a proton (H+) through an ionization process, typically in the gas phase. This results in a positively charged ion with a mass one unit greater than the neutral molecule. Protonated molecules are frequently observed in mass spectrometry, particularly in techniques like chemical ionization.",
