  "id": "MLC-T-CHM-005335",
  "term": "Hole burning",
  "field": "Chemistry",
  "definition": "A spectroscopic technique where a narrow spectral feature, or 'hole', is created in the absorption band of a material by selectively exciting a subset of molecules with a monochromatic light source. This process typically occurs at low temperatures and allows for the study of homogeneous linewidths and spectral diffusion. It provides high-resolution spectroscopic information.",
