The indexes are divided into three sections: Molecular Formula, Alphabetical, Chemical Class. Each of these consists of two parts: the first covers spectra up to 1980, and the supplement covers 1981 to 1995; with 1996 covered in a separate appendix. Each index section indexes the five main sets of spectra. To avoid nomenclature problems, it's best to start with the Molecular Formula indexes. After locating your compound in the index, note the reference number from the appropriate column on the right, and then consult the appropriate Sadtler set and volume.
Example: you need to find the proton NMR spectrum of Benzophenone, 5-chloro-2-(methylamino)- . If you know that its molecular formula is C14H12ClNO, look up that formula in the formula indexes, and match the name. (This compound is in the Supplementary Index.) The NMR column shows that the spectrum is number 38148 in the NMR set . Note the other spectra types also available for this substance.
Compounds are listed in this index in Hill formula order: number of carbon atoms first, then hydrogen, then other non-metal atoms in alphabetical order, Br, Cl, F, I, N, O, P, S, and Si. Other elements are listed in the M column. Compounds without carbon are found at the end of the index. Compounds with the same formula are sorted alphabetically by name under that formula.
Compounds are listed alphabetically by name of parent compound, followed by derivatives. Nomenclature closely follows older Chemical Abstracts (pre-9th CI) standards, but is not exactly equivalent. Sadtler assigns the parent name on the basis of a predefined priority of functionality, with substituents and/or derivatives specified alphabetically after the parent name. Ignore numbers, Greek letters, and isomerism designators when searching the alphabetical sequence. In addition to systematized names, many cross-references to frequently used trivial names can also be found. (See the index's introduction for further examples and explanation.)
Various functional groups are assigned a numeric code, found in the chart in the front of the index. Compounds are listed in the index by the three lowest codes, found in the FUNCTIONALITY columns. Complex compounds are given special designations (e.g. Y5, Steroids) and are found at the end of the index. See the introduction for a more thorough explanation of this index.
Compounds are listed by increasing molecular weight, then alphabetically by name. If you know only the mol.wt. of an unknown, use this index to find a matching spectrum. This index contains only compounds that appeared in the Proton NMR set after 1981.
The IR "Spec Finder" indexes allow you to locate IR spectra based on absorption peaks. Consult their introductions for further information. The Carbon-13 set also has its own peak indexes.
The spectrum page itself includes the structural formula, with solvent, sample purity, source, and equipment information. The NMR, 13C and UV spectra also give assigned peaks.
