TL;DR: In this article, the manganese associated with photosynthetic oxygen evolution is suggested to occur as a bridged transition metal dimer with most likely another manganizer, and extensive details on the analysis are included.
Abstract: Extended X-ray Absorption Fine Structure (EXAFS) studies on the manganese contained in spinach chloroplasts and on certain di-u-oxo bridged manganese dimers of the form (X{sub 2}Mn)O{sub 2}(MnX{sub 2} (X=2,2'-bypyridine and 1,10-phenanthroline) are reported. From these studies, the manganese associated with photosynthetic oxygen evolution is suggested to occur as a bridged transition metal dimer with most likely another manganese. Extensive details on the analysis are included.

TL;DR: In this paper, the authors used extended x-ray absorption fine structure (EXAFS) as a probe for the study of catalysts and demonstrated the utility of EXAFS for very highly dispersed catalysts.
Abstract: In recent years the utility of extended x-ray absorption fine structure (EXAFS) as a probe for the study of catalysts has been clearly demonstrated [1–13]. Measurements of EXAFS are particularly valuable for very highly dispersed catalysts. Supported metal systems, in which small metal clusters or crystallites are commonly dispersed on a refractory oxide such as alumina or silica, are good examples of such catalysts. The ratio of surface atoms to total atoms in the metal clusters is generally high and may even approach unity in some cases. With such catalysts it is difficult or impossible to obtain structural information by conventional x-ray diffraction methods [14].

TL;DR: In this article, a simulation of the roto-translational collision-induced absorption spectra at frequencies from 0 to 250 cm(exp -1) was performed for the temperature range 200 to 800 K.

TL;DR: In this article, the exciton creation in Ge and Si by indirect and direct transitions has been obtained from high resolution absorption spectra, which is interpreted as being due to the formation of excitons and free electron-hole pairs.
