fingerprint region n. Chemistry (in infrared spectroscopy) a region of the spectrum in the range of wavelengths approx. 1500–500 cm⁻¹, in which a complex pattern of absorptions are found that are unique to the compound being analysed.

ΚΠ

1950 Science 26 May 579/1 The absorption of chloroform in the fingerprint region was so great, however, that positive identification from this region could not be made.

1987 K. A. Rubinson Chem. Anal. xx. 815 The fingerprint region contains peaks that arise from complicated normal modes involving bending motions.

2006 J. M. Hornback Org. Chem. (Internat. Student ed.) xiii. 513 The absorption due to the CN bond stretch is very difficult to use because it occurs in the fingerprint region with only weak to moderate intensity.
