Update Of NIST/EPA/NIH Mass Spectral Database

NIST 02 is the latest NIST/EPA/NIH Mass Spectral Database with more than 175,000 spectra and over 147,000 compounds. Every spectrum has been evaluated to produce a fully-evaluated database for the identification of unknown spectra. The database is offered in the common NIST format and versions that are compatible with most manufacturers' data systems. The program features multiple query options to match unknown spectra with identifiable compounds, and provides structure searching. Multiple user libraries can easily be created using Mol files. A built-in utility enhances the analysis and examination of user data files, and a special interpreter illustrates the fragmentation of a structure compared to observed peaks in the mass spectrum.
