Enter a wavenumber, and a list of possible functional groups with their intensities is displayed.

Enter a structure and a IR/Raman spectra is generated together with table of the important wavenumbers and IR/Raman intensities. When clicking on a wavenumber, the corresponding 3D normal vibration mode will be displayed.

Searchable (e.g. Formula, Name, Partial formula, CAS registry number, Molecular weight etc.) database with IR spectra for over 5000 compounds.

Newsgroup for discussion of all areas of spectroscopy.
