Structural determination of a highly branched C25 sedimentary isoprenoid biomarker by NMR spectroscopy and mass spectrometry
Abstract
The C25 diene 2,6,10,14-tetramethyl-7(3-methylpent-4-enyl)pentadec-5-ene has been isolated from benthic sediments and characterised by 1H and 13C NMR spectroscopy together with mass spectrometry.
