✦ Synopsis


Contrary to recent experimental evidence suggesting that the monoeyclic ring is the most stable 20-atom carbon species, highly accurate calculations convincingly predict that the smallest fullerene, dodecahedral C20, has the lowest energy. A related corannulene-like bowl is nearly degenerate in energy to the fullerene. Thermodynamic considerations suggest that at ~'c,rnation temperatures of around 700 K the bowl should be the dominant species.
