However, NIST makes no warranties to that effect, and NIST or absence), demonstrating the three different types of bonds that The complexity of infrared spectra in the 1450 to 600 cm-1 region makes it difficult to assign all the absorption bands, and because of the unique patterns found there, it is often called the fingerprint region. The following table provides a collection of such data for the most common functional groups. ! Further analysis (below) will show that this spectrum also indicates the presence of an aldehyde function, a phenolic hydroxyl and a substituted benzene ring.

Absorption bands in the 4000 to 1450 cm-1 region are usually due to stretching vibrations of diatomic units, and this is sometimes called the group frequency region. In alkanes, which have very few bands, each band in the spectrum can be assigned: Figure 3. shows the IR spectrum of octane.
