Popis:	Valence-to-core X-ray emission spectra have been measured for a number of chromium compounds such as oxides, carbides, borides, nitrides, phosphides etc. The experimental spectra are in good agreement with the calculated ones. They form the basis for a detailed analysis of the first coordination shell of Cr. The unique application of this technique for material chemistry and environmental science is illustrated by two very different examples. In the former case the presence of Cr–C bonds in the bulk structure of electrochemically deposited amorphous chromium coatings was confirmed. In the latter one we have shown that a contaminated soil sample most probably contains Cr carbides and/or phosphides from anthropogenic origin.
