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 ...

A UV–Vis Photoacoustic Spectrophotometer
Analytical Chemistry, 2014A 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‐/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.
