| 1 | Contribution to Structural Elucidation: Behaviours of Substructures Partially Defined from 2D NMR显示文摘Structural elucidation (automatic determination of the structure of a molecule from its spectra) is frequently hampered by combinatorial explosion when trying to assemble the identified substructures. We devised a new method which can avoid this pitfall by a systematic examination of allowed 13 C chemical shifts ranges for all substructures chemically possible and combined with a progressive pruning thanks to neighbouring relationships appearing from 2D NMR. This method is explained by a detailed example. | EPOUHE Celine 范波涛 袁身刚 PANAYE A. DOUCET J.P. | 2003 | Chinese Journal of Chemistry2003，21，10： | 1 |
