Is C2 cluster ingested by fullerene C60?

Magic and hot giant fullerenes formed inside ion irradiated weakly bound C60 clusters

“…In the present experiment, and in Ref. 26, the C 60 + peaks have tails toward larger masses ͑cf. Fig.…”

“…2͒ which are signatures of size-up processes to C 60+2k + ͑k Ͼ 0͒ and fragmentation in the spectrometer extraction field. 26 To further aid the interpretation of the results, we have performed high level density functional theory calculations ͑B3LYP/ 6-31G ‫ء‬ level of theory͒ 27 for the most stable C 60 -C 112 fullerene isomers ͑thus extending the results in relation to Ref. 28͒.…”

Chemistry of Energetically Activated Cumulenes—From Allene (H2CCCH2) to Hexapentaene (H2CCCCCCH2)

“…This can lead to resonantly stabilized free radicals (RSFRs) in which the free electrons are delocalized over several carbon atoms. During the last decade, the investigation of the synthetic routes and chemical reactivity of these RSFRs have received particular attention due to their role in the formation of the first aromatic ring species [49][50][51][52][53][54] and of polycyclic aromatic hydrocarbons (PAHs) in combustion flames. These molecules are also believed to play a critical role in the formation of soot during the combustion of hydrocarbon fuels under oxygen-poor conditions.…”

A crossed molecular beams study on the formation and energetics of the resonantly stabilized free i-C4H3(X2A′) radical and its isotopomers

“…Small, resonantly stabilized free hydrocarbon radicals have been proposed to be involved in the formation of the first aromatic ring species in combustion flames [1][2][3][4][5][6] and in the preparation of carbon-carbon composites [7]. Here, the reaction of the n-C 4 H 3 radical (HCCHCCH) with acetylene (C 2 H 2 ) is thought to lead to the synthesis of the first six-membered aromatic ring in combustion flames, i.e.…”
