1 1 1 1 ! jcamp-plot.js. The complexity of infrared spectra in the 1450 to 600 cm-1 region makes it difficult to assign all the absorption bands, and because of the unique patterns found there, it is often called the fingerprint region. Vanillin (99%), coumarin (99%), and ethyl vanillin (98%) were purchased from Sigma-Aldrich (St. Louis, MO, USA). The complexity of this spectrum is typical of most infrared spectra, and illustrates their use in identifying substances. To see the formaldehyde molecule display a vibration, click one of the buttons under the spectrum, or click on one of the absorption peaks in the spectrum. Question: Hi, Can you help me analyze this two IR spectrum? Surfaceselective detection is made possible by adsorbing 17Oenriched water on alumina nanorods. their IR spectra.
