  "id": "MLC-T-CHM-000924",
  "term": "Atropisomers",
  "field": "Chemistry",
  "definition": "Stereoisomers produced by hindered rotation about a single bond, where the energy barrier is large enough for each rotational form to be isolated as a separate compound. The forms do not interconvert at room temperature, so each is configurationally stable. The classic examples are biphenyls carrying bulky substituents at the ortho positions.",
