Abstract
The first Web-based version of the NIST X-ray Photoelectron Spectroscopy Database (XPSDB) is described. The current database, built from a relational database management system (RDBMS), contains critically evaluated data with over 19,000 line positions, chemical shifts, doublet splittings, and energy separations of photoelectron and Auger-electron lines. It is available free of charge to the public through the Internet at http://srdata.nist.gov/xps/.
