3.3.6.3 Infrared spectroscopy

Content	Opportunities for skills development
$Bonds in a molecule absorb infrared radiation at characteristic wavenumbers. ‘Fingerprinting’ allows identification of a molecule by comparison of spectra. Students should be able to: use infrared spectra and the Chemistry Data Sheet or Booklet to identify particular bonds, and therefore functional groups, and also to identify impurities. The link between absorption of infrared radiation by bonds in CO₂, methane and water vapour and global warming.$	$Students should be able to use data in the Chemistry Data Sheet or Booklet to suggest possible structures for molecules.$
