ab·sorp·tiv·i·ty (ab″sorp-tivґĭ-te) a measure of the amount of light absorbed by a solution, defined as the absorbance per unit concentration per unit length of light path. By Beer's law (q.v.) absorptivity is proportional to the concentration of the absorbing solute. Called also absorbancy index, absorption constant, absorption coefficient, and extinction coefficient.
