Fingerprint region in ir spectra
WebIt's just that a spectrum is usually divided into a region where there are few absorptions (the diagnostic region) and a region where there are so many lines that it is difficult to say what causes them (the fingerprint region). … WebThe region of the infrared spectrum from 1200 to 700 cm -1 is called the fingerprint region. This region is notable for the large number of infrared bands that are found there. Many different vibrations, including C-O, C-C …
Fingerprint region in ir spectra
Did you know?
Webmotions, and accordingly, an IR spectrum is usually complex. • The region from about 1400 – 600 cm−1 is called the fingerprint region and is hard to interpret. It is a very complex absorption pattern, and if two molecules give the same fingerprint, they are most likely the same molecule. • However, one region of the IR spectrum, from about WebThis part of the spectrum is called the fingerprint region. Although this region is not very useful for detecting which functional groups are present, it can still be useful for …
WebThe carbon-carbon bond has absorptions which occur over a wide range of wavenumbers in the fingerprint region - that makes it very difficult to pick out on an infra-red spectrum. … WebNov 8, 2024 · 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 …
