Eight most abundant ions in 81,000+ mass spectra, indexed by molecular weight, elemental composition, and mass-to charge ratio of the eight most abundant ions. Each entry also provides the relative intensities of the eight most abundant ions plus the parent ion, molecular formula, compound name, CAS registry number when available, and the code for the source spectrum.

Compiled by the NBS, this collection contains over 25,000 verified mass spectra in bar graph format, with CA index name, molecular formula, mol. wt., structural formula, and registry number. Arranged by increasing mol. wt. The index volume covers the set and its first supplement, by name, formula, mol. wt., and registry number. (Supplement 2 is on microfiche.) This set was later revised as and superseded by the Wiley/NBS registry of mass spectral data (see below).
Spectra are arranged in order of increasing molecular weight, then by molecular formula. Indexes in vol. 7 for compound names, molecular formulas, and CAS registry numbers. No peak indexes. This set is a revision and expansion of the NIH/EPA mass spectral database published by the NBS 1978-80.
