Important Peak Index Of The Registry Of Mass Spectral Data Three Volume Set

While covering the same spectra as the NBS registry of mass spectral data (Wiley, c.1989), this set presents the information differently to facilitate different usage. It selects from each spectrum only those peaks which are most diagnostic of the chemical in question. Some 400,000 entries facilitate interpretation of unknown spectra from the broadest possible range of chemical types with peaks listed according to statistical importance and abundance. Includes peaks that are most useful for interpretation (these are not always the strongest peaks). A total of 136,141 spectra appear three times, arranged according to the mass of their first, second, and third most important peaks (highest U & A values). Within each listing the entries are ordered by the mass of the other most important peaks. Each entry lists, for the six most important peaks (in descending order of U + A values), the mass and percent abundance (equal to or greater than 1%). The molecular ion peak (that containing the most abundant isotopes) is also listed, giving its mass and abundance values (these abundances include 0.1%-0.9%; for less than 0.05%, no value is shown). Other data include the Registry serial number, the location in the printed Registry , the elemental composition (molecular formula), the CAS Registry number, and one or more names. A reference of great utility. Annotation copyright Book News, Inc. Portland, Or.

Fred Warren McLafferty is an American chemist known for his work in mass spectrometry. He is best known for the McLafferty rearrangement reaction that was observed with mass spectrometry. With Roland Gohlke, he pioneered the technique of gas chromatography-mass spectrometry. Douglas B. Stauffer is the author of The Important Peak Index of the Registry of Mass Spectral Data, 3 Volume Set, published by Wiley.
