Spin-lattice relaxation time

  "id": "MLC-T-CHM-011215",
  "term": "Spin-lattice relaxation time",
  "field": "Chemistry",
  "definition": "The characteristic time constant for the return of the nuclear spin system to thermal equilibrium with its surroundings (the lattice) after a perturbation. This process involves the exchange of energy between the spins and the molecular environment. It is denoted as T1 and is a measure of how quickly the longitudinal magnetization recovers.",
  "synonyms": [
    "spin-lattice time constant"
