Question

define finger print regiorr?

Answer 1

Answer:

The region between 400 cm-1 and 1500 cm-1 in an IR spectrum is known as the fingerprint region. It usually contains a large number of peaks, making it difficult to identify individual peaks. However, the fingerprint region of a given compound is unique and, therefore, can be used to distinguish between compounds.

Answer 2

The region between 400 cm⁻¹ and 1500 cm⁻¹ in an IR spectrum is known as the fingerprint region.

The importance of the fingerprint region is that each different compound produces a different pattern of troughs in this part of the spectrum.

Using the fingerprint region. Compare the infra-red spectra of propan-1-ol and propan-2-ol. Both compounds contain exactly the same bonds.
