fingerprint region

The fingerprint region is more specific to an individual compound.

It is called the molecular fingerprint region.

Even though 1-propanol and 2-propanol have similar infrared spectra in the functional group region, they differ in the fingerprint region.

This range is sometimes called the fingerprint region, since the mid-infrared absorption spectrum of a compound is very specific for that compound.

The enzyme contains five fingerprint regions containing Gln-Trp motifs, which are also present in the highly analogous bacterial enzyme squalene-hopene cyclase.

Residues of these fingerprint regions contain stacked sidechains which are thought to contribute to enzyme stability during the highly exergonic cyclization reactions catalyzed by the enzyme.

The second part of the infrared spectrum is called the fingerprint region; it is associated with types of motion allowed by the symmetry of the molecule and influenced by the bond energies.

Femtosecond infrared pulses can be used to determine which bonds in a molecule break or form. The mid-infrared fingerprint region is ideally suited to determine the presence of specific molecules in a sample.
