(I think that is how it is written!) But how do the numbering schemes get 2,3,7,8? How are the ``terminal nodes'' on the carbon backbones (or the carbon backbones themselves) numbered in a compound like this? And shouldn't the rings be shown as a ``resonance structure''? (or should they?) Mark Terribile hou5e!mat
