Stationary state

  "id": "MLC-T-CHM-011341",
  "term": "Stationary state",
  "field": "Chemistry",
  "definition": "A state of a system in which all observable properties are constant over time. In quantum mechanics, a stationary state corresponds to an eigenstate of the Hamiltonian operator, meaning its probability density does not change. This differs from a steady state, where macroscopic properties are constant but microscopic processes continue.",
