Aldrich Spectral Viewer

The Aldrich Spectral Viewer is an electronic reference book on CD-ROM that contains thousands of actual spectra from the Aldrich spectral libraries. This easy-to-use software program is more powerful than a printed book, allowing text and data field searching and the manipulation, printing, and exporting of spectra.

Currently, we offer one FT-IR library (over 11,000 compounds), one Aldrich/SensIR® ATR-IR library (over 18,000 compounds), one FT-Raman library (over 14,000), and two FT-NMR libraries (over 15,000 compounds) to suit your needs. The libraries can be used individually or can be combined to create a powerful, electronic reference. A single user interface handles both IR and NMR spectra, simplifying the use of the software. In addition, the Spectral Viewer is expandable so that when new spectral libraries are released, they can be easily added to the software.


  • Displays FT-IR spectra in % Transmittance or Absorbance along with chemical structure and technical data
  • Text Searching by Chemical Name, Aldrich Catalog Number, CAS Number, and Molecular Formula
  • Advanced data field searching on Chemical Category and physical properties such as Boiling Point, Melting Point, Density, Flash Point, Molecular Weight, and Refractive Index
  • Spectra processing using Zoom and Peak Labeling
  • Print spectra, structure, technical data, and peak listings
  • Export spectra to a file (Bitmap, Metafile, or JPEG formats) or to the clipboard (Bitmap or Metafile formats)
  • Web link button provides additional technical data from the Sigma-Aldrich Website
  • Fully compatible with Aldrich Spectral Viewer FT-NMR libraries - further enhance the utility of this powerful electronic reference with the addition of our FT-NMR libraries
  • Expandable - As new spectral libraries become available they can be added at a minimal fee with no subscription or maintenance fees required
