T O MEET YOUR CHANGING NEEDS FASTER A N D EASIER
You can locate and interpret an infrared spectrum in minutes by using the Sadtler Standard Reference Spectra. The Sadtler SPEC-FINDER lists Sadtler Standard Spectra in a numerical absorption-band system. The comparison spectrum for an unknown is found simply by turning to the section of the index listing the strongest band. Location of some of the remaining bands then gives the serial number of the standard spectrum. You are also given the chemical name, empirical formula, molecular structure, source of test sample, size and nature of sample, and more. Sadtler Standard Reference Spectra are available in 25 volumes covering 22,000 spectra.
HOW TO IDENTIFY 22,000 IR
SPECTRA
QUICKLY EASILY
ACCURATELY
SADTLER SPECTRA ARE INDEXED BY: ALPHABETICAL—Chemical Abstract nomenclature, classified by parent compounds, followed by substituent derivatives • MOLECULAR FORMULA—increasing orderof carbon, hydrogen and other atoms • CHEMICAL CLASS—permitting location of any single spectrum or class by functional g r o u p " NUMERICAL —by Sadtler Serial N u m b e r » SPEC-FINDER-for Standard IR or Commercial IR. Systematic classification of each by major absorption bands in each micron region and strongest band per spectrum. Coded numerically to locate unknown spectra from more than 30,000 in the Sadtler series. A l s o indexed in the Sadtler Computer System and the A S T M - I B M cards.
