Simulation of the UV/Vis spectra of flavonoids
2015 IEEE 15th International Conference on Bioinformatics and Bioengineering (BIBE), 2015The UV/Vis properties of 14 naturally occurring flavonoids, including flavones, flavonols, and isoflavones, were investigated. The TDDFT approach in combination with the B3LYP method and 6–311+G(d, p) basis set was applied. To avoid the Kohn-Sham orbitals, whose shapes are misleading when used to interpret and describe electronic transitions, the ...

UV/Vis‐/Fluoreszenz‐Spektroskopie
Nachrichten aus Chemie, Technik und Laboratorium, 1994AbstractDie UV/Vis‐Spektroskopie eignet sich in Verbindung mit chemometrischen Verfahren auch zur quantitativen Bestimmung von Substanzgemischen. Die als Simultandetektoren in der Flüssigkeitschromatographie eingesetzten Diodenarrays beginnen in der Routineanalytik, sequentielle Geräte zu verdrängen.
