Collision broadening

  "id": "MLC-T-MET-004515",
  "term": "Collision broadening",
  "field": "Meteorology and atmospheric science",
  "definition": "The widening of spectral lines in atmospheric absorption or emission spectra due to collisions between molecules. These collisions perturb the energy levels of the molecules, leading to a distribution of frequencies rather than a single sharp frequency. Collision broadening is dependent on pressure and temperature, increasing with higher pressure and lower temperature.",
