Say you're lecturing on chemical shifts and how integrals can provide information about the number and type of hydrogens contained in a molecule. You mention spin-spin splitting and then - with a few keystrokes or mouse clicks - you display the spectra, mark the triplet and quartet with splitting trees, measure integrations and enter them on the note pad. Then you display a series of screens that neatly summarize the n+1 rule.

It's that easy when you're using Spectral Interpretation!

Dozens of graphic screens loaded with information are built right into this easy-to-use program.

You can quickly alternate between IR and NMR spectra, measure coupling constants and integration curves on-screen, choose highlight and zoom options or dozens of other dynamic lecture aids.

The program is shipped with data and sprectra for 186 organic compounds representing major functional groups and these unique features:

• Choose by name/functional group or as
...an unknown

• Toggle quickly between IR & NMR spectrum.

• Display the structure. (For unknowns,
...structure is hidden.)

• Highlight any portion of the display.

• Label structure or spectrum.

• Integrate NMR spectrum

• Measure coupling constants.

• Show functional groups or structural
...fragments.

• Display splitting "trees".

• Store/recall notes for interpretation
...of each compound.

...useful both for student and instructor. The software can be used directly in class to discuss various features of infrared and NMR spectra. For student use, the software acts as a tutorial in which students can either study known spectra or try to solve unknowns . Spectral Interpretation is a good software package for studying the use of NMR and IR spectra for the purpose of structural determination of organic compounds.
