WebAug 20, 2014 · A correction factor for ablation algorithms assuming deviations of Lambert-Beer’s law with a Gaussian-profile beam Appl. Phys. Lett. 100 , 173703 (2012); 10.1063/1.4707389 WebBeer’s law suggests that a plot of absorbance vs. concentration—we will call this a Beer’s law plot—is a straight line with a y-intercept of zero and a slope of ab or \(\varepsilon b\). In some cases a Beer’s law plot deviates from this ideal behavior (see Figure 3.2.3 ), and such deviations from linearity are divided into three ...

The concentration dependence of absorbance can deviate from linearity, even in the ... WebMay 15, 2024 · These effects can sometimes not easily be differentiated from deviations of Beer's law caused by optical effects like electromagnetic wave interference in thin layers [[14], [15], [16]] or liquid cells [17]. In addition to these “chemical” or optical causes, local field effects contribute increasingly at higher concentrations [[18], [19]].
