Isooptoacoustic point

  "id": "MLC-T-CHM-006210",
  "term": "Isooptoacoustic point",
  "field": "Chemistry",
  "definition": "A specific wavelength or frequency in a series of optoacoustic spectra where the optoacoustic signal of two or more species is identical. This point indicates that the total concentration of the absorbing species remains constant throughout a reaction or titration. The presence of an isooptoacoustic point suggests a simple equilibrium between two components or a reaction with a fixed stoichiometry.",
