Publisher's Synopsis
This fourth edition of a major reference work contains 58,108 spectra of 48,357 compounds on 235 microfiche. It is time-tested and designed for maximum ease of use.;Each compound is represented in a standardized form with a structural diagram with any divergent spectra compiled under one entry number. A novel substructure code facilitates direct access to ring systems or single atoms with specific environments. Thirteen indexes make every piece of information readily accessible. These indexes contain chemical names, molecular formulae and weights, CAS Registry Numbers, literature references, structure vs. coupling constants, coupling constants vs. structure, relaxation times, chemical shifts, and substructure codes. The indexes all lead to the numbers under which compounds are registered in the data section and are designed to provide fast and easy access to the desired spectral information.
