  "id": "MLC-T-CHM-006172",
  "term": "Isoclinic point",
  "field": "Chemistry",
  "definition": "A point in a family of absorption spectra, recorded as a reaction or titration proceeds, where every curve has the same slope, meaning the first derivative with respect to wavelength is common to them all. It is the first-derivative counterpart of the isosbestic point, where the absorbance itself is common to all curves.",
