Carbyne trefoil knots - are they stable enough to exist?

Dobrowolski J.Cz., Mazurek A.P.

Polish Journal of Chemistry

1998

Vol. 72, nr 7S

1593-1603

The structure and stability of non-linear carbon clusters of carbyne type was estimated based on ab initio quantum mechanical calculations. Both the cyclic (cacarbynes) and knotted (knocarbynes) trefoil structure of closed polycarbon chains, containing up to 84 carbon atoms, were considered. Comparison of the calculated spectral properties (IR, (13)C NMR) with those of C60 fullerene provide the basis for experimental identification of Cn cyclic and knotted structures as may have implication for interstellar dust spectroscopy.
