Peak fitting

{
  "id": "MLC-T-CHM-008568",
  "term": "Peak fitting",
  "field": "Chemistry",
  "definition": "A mathematical procedure used to decompose a complex spectral band into its individual component peaks. This process involves modeling each peak with a specific function, such as a Gaussian or Lorentzian, and adjusting parameters like position, height, and width to achieve the best fit to the experimental data. The method is widely applied in X-ray photoelectron spectroscopy to identify chemical states.",
