remarks - The original building blocks of this fossil natural resin are mainly terpenoids containing carboxylic acid, ester, aldehyde, keto and/or hydroxyl functional groups, which on fossilisation have been condensed and vinyl-polymerised. Further modifications may have been introduced by dehydration, decarboxylation and dehydrogenation. The complex Py-MS patterns of ambers (ref. 207) contain series of unsaturated hydrocarbon and aldehyde fragments. Prominent ion series at odd mass numbers (EI fragments) point to a mainly branched-aliphatic character of the pyrolysis fragments.
