| Abstract: | Highlights: [•] Intramolecular 13C isotopic distribution in n-alkanes determined via isotopic 13C NMR. [•] Relative isotopomer concentration of the three terminal carbon atom positions available. [•] Alternation of intramolecular 13C pattern between odd and even heavy n-alkanes. [•] Strong 13C depletion on the methyl position of light n-alkanes. [•] Promising tool for the study of the sources and sinksof n-alkanes. [Copyright &y& Elsevier] |
