The use of Wronskian determinants in the study of multicomponent systems is proposed. The general theory is presented and applied to the spectrophotometric determination of the number of linearly independent components–absorbers. A detailed study of a two‐component system is presented and analysed. Numerical methods for smoothing and differentiation of digitized spectra via cubic splines are used.
