Carbon (1s) NEXAFS spectra of biogeochemically relevant reference organic compounds
Solomon, Dawit; Lehmann, Johannes
Natural organic matter (NOM) is a significant and active component in soils and sediments and plays an important role in carbon cycling. This data set provides a library of carbon (1s) near-edge X-ray absorption fine structure (NEXAFS) spectra of biogeochemically relevant reference organic compounds. These spectral features can be used to derive structural information and determine peak assignment criteria to aid in the identification of complex organic carbon compounds in environmental samples. Comprehensive information on this research is presented in the following publication: Solomon, Dawit, Johannes Lehmann, James Kinyangi, Biqing Liang, Karen Heymann, Lena Dathe, Kelly Hanley, Sue Wirick, and Chris Jacobsen. 2009 (In press: vol. 73).

This study was financially supported by grants from the NSF- Division of Environmental Biology (DEB-0425995), the Coupled Natural and Human Systems Program of the Biocomplexity Initiative of the NSF (BCS-0215890) and USDA-CSREES (2002-35107-122269). Any opinions, findings, and conclusions or recommendations expressed in this material are those of the authors and do not necessarily reflect the views of USDA or the National Science Foundation. The C (1s) NEXAFS data under the project No. 4988 was collected using the X-1A1 STXM developed by the group of J. Kirz and C. Jacobsen at SUNY Stony Brook with support from the Office of Biological and Environmental Research, U.S. Department of Energy under contract DE-FG02-89ER60858, and the NSF under grant DBI-9605045. The zone plates were developed by S. Spector and C. Jacobsen of Stony Brook and D. Tennant of Lucent Technologies Bell Labs, with support from the NSF under grant ECS-9510499.
