In astronomy, the term spectrophotometry refers to the measurement of the spectrum of a celestial object in which the flux scale of the spectrum is calibrated as a function of wavelength, usually by comparison with an observation of a spectrophotometric standard star, and corrected for the absorption of light by the Earth's atmosphere.
An example of an experiment in which spectrophotometry is used is the determination of the equilibrium constant of a solution.A certain chemical reaction within a solution may occur in a forward and reverse direction where reactants form products and products break down into reactants.t is more specific than the general term electromagnetic spectroscopy in that spectrophotometry deals with visible light, near-ultraviolet, and near-infrared, but does not cover time-resolved spectroscopic techniques.
