  "term": "Deuterium",
  "field": "Chemistry",
  "definition": "An isotope of hydrogen, often symbolized as D or 2H, containing one proton and one neutron in its nucleus. It is approximately twice as heavy as protium (1H), the most common hydrogen isotope. Deuterium is widely used as a tracer in chemical reactions and in nuclear magnetic resonance spectroscopy due to its distinct nuclear spin properties.",
