  "term": "R, S",
  "field": "Chemistry",
  "definition": "A system of stereodescriptors used to denote the absolute configuration of a chiral center in a molecule. The R (rectus) and S (sinister) designations are assigned based on the Cahn-Ingold-Prelog priority rules for substituents around the chiral center. This system provides an unambiguous way to describe the three-dimensional arrangement of atoms.",
