Abstract
Determination of the number of absorbing chromophores in light-scattering media is illustrated in this experiment. Diffuse Reflectance Spectroscopy is used to evaluate this quantity, both for a solid and for a suspension. Results are compared with the absorbance spectrum of the chromophore in a transparent nonscattering matrix.
