A UV–Vis Photoacoustic Spectrophotometer

Analytical Chemistry, 2014
A novel photoacoustic spectrophotometer (PAS) for the measurement of gas-phase and aerosol absorption over the UV-visible region of the spectrum is described. Light from a broadband Hg arc lamp is filtered in eight separate bands from 300 to 700 nm using bandpass interference filters (centered at 301 nm, 314 nm, 364 nm, 405 nm, 436 nm, 546 nm, 578 and ...

UV/VIS-Spektroskopie

1990
Die UV/VIS-Spektroskopie befasst sich mit der Wechselwirkung zwischen elektromagnetischer Strahlung und anregungsfahigen Elektronensystemen in Molekulen oder Ionen. Die UV-Spektroskopie umfasst den Strahlungsbereich der Wellenlangen 200 bis 400 nm, die VIS-Spektroskopie 400 bis 800 nm.

UV-Vis Spectroscopy

2013
In a UV-Vis (ultraviolet-visible light) spectroscopic measurement, light absorption as a function of wavelength provides information about electronic transitions occurring in the material. For semiconductors, UV-Vis spectroscopy offers a convenient method of estimating the optical band gap, since it probes electronic transitions between the valence ...

Simulation of the UV/Vis spectra of flavonoids

2015 IEEE 15th International Conference on Bioinformatics and Bioengineering (BIBE), 2015
The 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 ...
