Analytical Applications of UV-VIS Spectroscopy
1992For about 130 years, the Bouguer-Lambert-Beer law has been used as the quantitative basis of absorption spectroscopy. Bouguer established empirically a correlation between pathlength and light absorption in 1729. This correlation was then formulated mathematically by Lambert in 1760 [1] and Beer discovered the dependence upon the concentration in 1852 [

The rapid identification of organic colorants by UV/vis spectroscopy
Analytical and Bioanalytical Chemistry, 2002A rapid UV/vis spectroscopic method for the identification of organic colorants by the use of Gaussian analysis is presented. Sets of parameters are obtained for the screening with a low number of data. An optical distance using line positions and intensities is defined as a measure for the similarity of UV/vis spectra.

UV-VIS-NIR spectroscopy and microscopy of heterogeneous catalysts
Chemical Society Reviews, 2010This critical review article discusses the characterization of heterogeneous catalysts by UV-VIS-NIR spectroscopy and microscopy with special emphasis on transition metal ion containing catalysts. A review is given of the transitions, that can be observed in the UV-VIS-NIR region and the peculiarities of catalytic solids that have to be taken into ...
