WebNIR spectra contain a wealth of information about the chemical and physical properties of a sample, which however require considerable effort to be deducted from the spectra. Because NIR is composed of overlapping overtones and combinations of bands originating in the mid-IR, chemometric data analysis algorithms are used.

In vibrational spectroscopy, an overtone band is the spectral band that occurs in a vibrational spectrum of a molecule when the molecule makes a transition from the ground state (v=0) to the second excited state (v=2), where v is the vibrational quantum number (a non-negative integer) obtained from solving the Schrödinger equation for the molecule.
