Analytical Chemistry publication accepted as Supplementary Cover Art!

Updated: Jul 12, 2023

We are thrilled to announce that the 2nd part of our 3-part manuscript series on the effects of cascading optical processes has been featured on the cover of Analytical Chemistry!


This work (Part II) studies the effects of light scattering AND absorption on a series of optical spectroscopic measurements in samples containing both absorbers and scatterers, but not emitters. The experimental UV-vis spectrum in theses samples was the sum of the sample absorption and scattering extinction; however, the upper limit of the experimental Beer's-law-abiding extinction is limited prematurely by the interference of forward scattered light. Our research found that light scattering decreases light absorption along the optical path length from the excitation source to the UV-vis detector. However, since scattered light is absorbed along the optical path, its impact on the total light absorption is negligible (<10%). These findings serve as important validation of our recently developed integrating-sphere-assisted resonance synchronous spectroscopy method, which decouples sample absorption and scattering from the double beam UV-vis extinction (https://doi.org/10.1021/acs.analchem.2c02037).
