Talk:Dicoronylene

References[edit]

Everything I added, the history, occurence, etc. are all detailed with the original cited literature in the book that is referenced. I can add all of those if that would be useful.

This compound has been studied quite a lot for a large PAH, which I thought it should have its own article. Astrophysicists have been especially interested in it.

Thanks Fetz, I do not think there is a need to give all the literature cited here if the main source is the reference given in the article. V8rik 20:54, 17 September 2007 (UTC)[reply]

Right, but the references are easy incorporated if questions arise and the talk page is a good place to store them in case they are needed. --Stone 08:16, 18 September 2007 (UTC)[reply]

Ball-and-stick picture is incorrect[edit]

It is not possible to draw a resonance structure of dicoronylene with a double bond bridging the two coronene moieties. The bonds connecting the two moieties should be drawn as pure single bonds.

(Proof: any such resonance structure must either have one or both bridging bonds written as double. If only one bridging bond is double, then each coronene moiety must contain 11 1/2 pi bonds - impossible. If both bridging bonds are written as double, all of the double bonds are locked as horizontal and the two ends are left hanging.) Magic9mushroom (talk) 06:58, 15 November 2019 (UTC)[reply]
