Isosbestic point

{
  "id": "MLC-T-CHM-006214",
  "term": "Isosbestic point",
  "field": "Chemistry",
  "definition": "A specific wavelength at which the molar absorptivity of two or more components in a chemical system is identical. This phenomenon occurs when a chemical reaction or equilibrium involves the interconversion of two species, and the total concentration of these species remains constant. The presence of an isosbestic point indicates a simple two-component equilibrium or reaction without intermediate species accumulating.",
