  "id": "MLC-T-CHM-010953",
  "term": "Smectic",
  "field": "Chemistry",
  "definition": "Describing a liquid-crystal state, or mesophase, in which the constituent molecules exhibit both orientational order and positional order in one dimension. The molecules align their long axes in a preferred direction and are arranged into distinct layers. Within these layers, the centers of mass are disordered, giving the phase liquid-like properties in two dimensions.",
