  "id": "MLC-T-CHM-010903",
  "term": "Singlet state",
  "field": "Chemistry",
  "definition": "An electronic state of an atom or molecule where all electron spins are paired, resulting in a total spin angular momentum of zero. In this state, the spin multiplicity, calculated as 2S+1 (where S is the total spin quantum number), is equal to one. Many organic molecules exist in a singlet ground state.",
