text: The naturality of different aroma can also be checked using SNIF-NMR: for example for anethole, abundance of only six monodeuterated isotopomers can be measured by H-SNIF-NMR that allows differentiating the botanical origins fennel, star anise or pine.
  Other applications:
  The SNIF-NMR applied to benzaldehyde can detect adulterated bitter almond and cinnamon oils. It is demonstrated that the site specific deuterium contents of benzaldehyde allow the determination of the origin of the molecule: synthetic (ex-toluene and ex-benzal chloride), natural (ex-kernels from apricots, peaches, cherries and ex-bitter almond) and semisynthetic (ex-cinnamaldehyde extracted from cinnamon).
  Other applications have also been published: raspberry ketone), heliotropine, ...
