Fingerprint region in ir spectra
WebJun 1, 2024 · The mid-IR spectral region, from 2 to 20 µm, is called the molecular-fingerprint region, because most molecules have intense fundamental vibrational bands there. The IR spectrum of a given molecule thus provides a unique way to non-intrusively identify and quantify that molecule in any phase of matter. WebFingerprint region: The 1450 - 500 cm-1 range of an infrared spectrum. Called the fingerprint region because (like a human fingerprint) this region of the spectrum is almost unique for any given compound.
