WebNov 9, 2024 · IR spectra can be divided into two main regions: Diagnostic region – generally has fewer peaks and provides the clearest information. This region contains all signals that arise from all bonds in a molecule. Fingerprint region – contains signals resulting from the vibrational excitation of most single bonds (stretching and bending).; Since the fingerprint … WebSpectral Library Search. The infrared spectrum of a molecule is like a fingerprint. By comparing the spectrum of an unknown compound to a library of data, the spectroscopist can identify the unknown. This technique has wide applications in many fields such as forensics, environmental chemistry, research, industrial quality control, and teaching. WebInteractive tools aid spectral interpretation (placing cursor on the IR peak highlights the related structural fragment).
