  "id": "MLC-T-CHM-010795",
  "term": "Shakeup",
  "field": "Chemistry",
  "definition": "A process accompanying an inner-shell ionization event where an outer-shell electron is simultaneously excited to a higher unoccupied orbital. This excitation leads to a loss of kinetic energy for the ejected photoelectron, appearing as satellite peaks at lower kinetic energy in X-ray photoelectron spectroscopy. It provides information about the electronic structure and bonding of the atom.",
