AIP announces that the Journal of Physical and Chemical Reference Data is available online, for the first time, beginning February 2000. Please note that all print subscribers are entitled to online access at no extra charge. All data are fully documented with original sources and the criteria used for evaluation. Resulting from a critical evaluation of the published literature, the database contains over 19,000 line positions, chemical shifts, doublet splittings, and energy separations of photoelectron and Auger-electron lines. A highly interactive program allows the user to search by element, line type, line energy, and many other variables.
Users can easily identify unknown measured lines by matching to previous measurements.
Data are included for observed transitions of 99 elements and energy levels of 52 elements. The most current NIST-evaluated data associated with each transition are integrated under a single listing. The February 2000 release of The NIST WebBook is the sixth edition of the NIST Chemistry WebBook . There are many avenues for searching the database. Structures are given for most species, as well as common and commercial names.
