Organic chemistry and instrumental analysis.eiii) deduction of the structures of organic compounds from different analytical data including: iii) IR spectra.Module 6: Organic chemistry and analysis.be able to use data from infrared spectra to deduce functional groups present in organic compounds and to predict infrared absorptions, given wavenumber data, due to familiar functional groups, including: C–H stretching absorption in alkanes, alkenes… Topic 7: Modern Analytical Techniques I.Students should be able to: use infrared spectra and the Chemistry Data Sheet or Booklet to identify particular bonds, and therefore functional groups, and also to identify impurities. We briefly explain the fundamentals of infrared (IR) spectroscopy and focus on the basic questions about FT-IR, ATR, transmission and reflection.‘Fingerprinting’ allows identification of a molecule by comparison of spectra. A graph is produced showing how the percentage transmittance varies with the frequency of the infra-red radiation.Bonds in a molecule absorb infrared radiation at characteristic wavenumbers.(It should be noted that these techniques are applicable not only to organic chemistry but also to many other areas of chemistry.) Brief reference to the principles of each method.Infra-red absorption spectrometry (IR) as a 'fingerprinting' technique involving absorption of infra-red radiation (reference to molecular vibrations not required).
