WebAbsorbance Is Related to Concentration and Distance This property is applied in scientific experiments. By measuring how much light is absorbed as the light passes through a liquid, we can measure the amount of substance contained or the progress of the reaction. There are two factors involved in absorbance: concentration and distance. WebThe UV absorbance spectra of the bases (Fig. 1) look as if there are two simple bands; however, each “simple” band observed is a composite of more than one transition. This makes detailed analysis of DNA absorption difficult, but usually ensures that the absorption spectrum changes when the system is perturbed in any way, thus making ...
