Solvent shift

  "id": "MLC-T-CHM-011030",
  "term": "Solvent shift",
  "field": "Chemistry",
  "definition": "A change in the position of an absorption or emission band in a spectrum, typically observed in ultraviolet-visible or infrared spectroscopy, when the solvent is changed. This shift results from differential stabilization of the ground and excited states by solvent-solute interactions. A shift to longer wavelengths is called a bathochromic shift, while a shift to shorter wavelengths is a hypsochromic shift.",
