WebParts of an FTIR spectrometer with source, interferometer, and detector. The source is typically a broadband emitter such as a mid-IR ceramic source (50-7,800 cm -1 ), a near-IR halogen lamp (2,200 – 25,000 cm -1 ), or a far-IR mercury lamp (10-700 cm -1 ). WebHydrocarbons compounds contain only C-H and C-C bonds, but there is plenty of information to be obtained from the infrared spectra arising from C-H stretching and C-H bending. In alkanes, which have very few bands, each band in the spectrum can be assigned: C–H stretch from 3000–2850 cm-1; C–H bend or scissoring from 1470-1450 cm-1
WebApr 1, 2002 · The IR-spectrum can be divided into five ranges major ranges of interest for an organic chemist: a. From 2700-4000 cm-1(E-H-stretching: E=B, C, N, O) In this range typically E-H-stretching modes are observed. The C-H-stretching modes can be found between 2850 and 3300 cm-1,depending on the hydrization. WebAn example of such a spectrum is that of the flavoring agent vanillin, shown below. The complexity of this spectrum is typical of most infrared spectra, and illustrates their use in identifying substances. The gap in the spectrum between 700 & 800 cm -1 is due to solvent (CCl 4) absorption.
