  "id": "MLC-T-CHM-001106",
  "term": "Band shape",
  "field": "Chemistry",
  "definition": "The characteristic profile of an absorption or emission band in a spectrum, determined by factors such as natural linewidth, Doppler broadening, and pressure broadening. It describes the intensity distribution as a function of wavelength or wavenumber. The band shape provides information about the molecular environment and interactions within a sample.",
