Which of the following relationships is not valid as applied to ultraviolet-visible spectroscopy?

Question

Quizplus · Accepted Answer

The correct relationships for ultraviolet-visible spectroscopy include A = log (I_o/I), which is a form of the Beer-Lambert law, A = εcl (where A is absorbance, ε is the molar absorptivity, c is the concentration, and l is the path length), and ΔE = hν (which relates the change in energy to the frequency of light, with h being Planck's constant). The choice D, A = λ_maxl, does not represent a valid or recognized relationship in the context of UV-visible spectroscopy.
