A Random Number Model for Beer's Law - Atom Shadowing

Screening hypochromism (sieve effect) in red blood cells: a quantitative analysis

“…It is important to point out that, whatever the absorbing entity, the BLB law takes account of shadowing of an entity by another entity lying closer to the front of the absorption cuvette [7,8].…”

A More Pedagogically Sound Treatment of Beer's Law: A Derivation Based on a Corpuscular-Probability Model

“…After determining the expected results of each model, we may turn to experimentally obtained results to see which (if either) model is consistent with observation. If time and logistics permit, the presentation of Beer's law may be integrated with a lab activity allowing students to test the models themselves, as suggested by Ricci et al (7). In the absence of an integrated lab activity, one may simply state that the predictions of the corpuscular-probability model are supported by experiment, present tabulated ("dry lab") data to support the correct model, or refer to a historical account.…”

Beer's Law Measurements Using Non-monochromatic Light Sources—A Computer Simulation

“…Beer's law quantitatively describes the absorption of radiant energy by absorbing species (1)(2)(3)(4)(5)(6)(7)(8)(9)(10). The derivation of Beer's law is given in many instrumental analysis (1, pp 33-39; 2, pp 123-135; 3), analytical chemistry (5; 7, p 515), and physical chemistry (8,9) textbooks and in this Journal (11)(12)(13)(14)(15)(16)(17)(18)(19), using different approaches. Application of Beer's law in chemical analysis is an essential part of the undergraduate chemistry curriculum.…”
