WebC60 was not observed in the desorbed material suggesting that complete cage closure cannot be achieved on HOPG. Furthermore, C60H21F9 deposits cannot be fully removed from HOPG. Instead, competing on-surface polycondensation of reactive intermediates yields a fluorinated carbon phase, which remains stable up to at least ∼1000 K. WebMatching polynomial and its zeros for the molecular graph of C70 are reported. Topological resonance energy (TRE) is calculated and compared with that reported for C60, and with the values obtained by conjugated circuits model. TRE values indicate slightly greater stability of C70, in agreement with recent experimental results. Web11 apr. 2024 · Enter the numbers in the image The numbers you entered don't match the image.
