The Cover Feature illustrates the connection between dispersion and absorption artistically, based on which Beer's law is derived from Maxwell's wave equation and the classical damped harmonic oscillator model (CDHO*). For a homogenous and isotropic medium, e = n 2 establishes an (almost) linear dependence of absorbance on the concentration. More information can be found in the Communication by T. G. Mayerhöfer and J. Popp on page 511 in Issue 4, 2019 (DOI: 10.1002/cphc.201801073).
