Über die Teilchengrössenabhängigkeit der Lichtabsorption in heterogenen Systemen. I. Theoretische Betrachtungen

Based on the laws of probability and light scattering being neglected, an equation is derived which describes the light absorption properties of concentrated and diluted monodispersed heterogeneous systems as a function of particle size. Taking into account the volume occupied by a single particle, it is shown that the particle distribution within a concentrated system can be described by a hypergeometric distribution function. The theory is extended to monodispersed systems containing particles of different absorption properties and also to diluted polydispersed systems.
