What compounds could possibly have at the absorbance of 250 to 315 in UV-Vis? 


Best insight from top research papers

Compounds with UV-Vis absorbance between 250 to 315 nm can include novel benzotriazoles, which are demonstrated to have useful UV-absorbing properties and are utilized as photostabilizers and solubilizers. Additionally, proteins like the synthetic 67 residue protein α3C, devoid of aromatic amino acids, exhibit distinctive absorption spectra in this range due to charge transfer transitions involving charged amino acid residues like Lys and Glu. These charged amino acids, constituting over 50% of the sequence composition in α3C, contribute significantly to the absorption beyond 250 nm, expanding the pool of spectroscopically active biomolecular chromophores. Therefore, compounds such as benzotriazoles and proteins like α3C can exhibit absorbance in the 250 to 315 nm range in UV-Vis spectra.
