Quality Data from Messy Spectra: How Isometric Points Increase Information Content in Highly Overlapping Spectra

Abstract

Dedicated to my newborn daughter.

Agglomeration compaction promotes corrosion of gold nanoparticles

“…2 ). 46 Indeed, the observation of isosbestic point indicates that the stoichiometry of the reaction remains unchanged over time and there is no competition between parallel reactions (such as, the dissolution of nanoparticles etc. ) occur within the considered time range (for more details see ESI † ).…”

Sorafenib and Piperine co-loaded PLGA nanoparticles: Development, characterization, and anti-cancer activity against hepatocellular carcinoma cell line

“…One of the advantages of this HPLC method is that no dual UV absorbance is needed because both SORA and PIP were well detected at 280 nm, which is considered the isosbestic point for both drugs. “An isosbestic point in spectroscopy is a particular wavelength (nm) at which two (or more) chemical substances or species have the same absorptivity” ( Kaspar, 2023 , Tiwari et al, 2020 ).…”

Nucleoside Phosphorylases make N7-xanthosine

“…These reactions were monitored at 288 nm (the isosbestic point of phosphorolysis of this transformation at pH 10) and 300 nm (near the maximum positive difference of the extinction coefficients, = 3.6 mM −1 cm −1 ) for 4 h. The resulting absorption data were converted to conversions and equilibrium states as detailed in the Supplementary Information, giving the reaction courses and the relationship shown in Fig. 1j, k 21 , 39 .…”
