  "id": "MLC-T-CHM-008071",
  "term": "Normal mode",
  "field": "Chemistry",
  "definition": "A collective, synchronous motion of atoms in a molecule where all atoms oscillate with the same frequency and phase. Each normal mode corresponds to a specific vibrational pattern and has a characteristic frequency. For a non-linear molecule with N atoms, there are 3N-6 normal modes of vibration.",
  "synonyms": [
    "normal vibration",
