Diocarbon is a diatomic neutral particle formed by two carbon atoms (C 2 ), and detected spectrometrically in an electric arc (along with some fullerenes ), in comets and in blue flames . [one]
Properties
Diocarbon can be obtained from graphite in an electric arc. It is also detected as a product by the reaction of tetrachlorethylene with sodium.
The C 2 molecule does not exist under normal conditions, since carbon is much more stable in the state of diamond , graphite or fullerene .
Comets
The light of weak comets is mainly radiation of diatomic carbon. The main part of the emission of C 2 molecules is in the visible spectrum. [2]
