Molecular fragment

{
  "id": "MLC-T-CHM-007493",
  "term": "Molecular fragment",
  "field": "Chemistry",
  "definition": "An ion or neutral species formed by the dissociation of a molecule, often as a result of ionization or other energetic processes. These fragments are detected in techniques like mass spectrometry, where the parent molecule breaks apart in a predictable way. The resulting mass spectrum, which shows the relative abundance of different fragments, serves as a fingerprint for identifying the original molecular structure.",
