Bottom Line: These provide insight into the influence of steric properties on the nature of physisorption.The enhanced stabilities of (C60)2 (+)(CO2)8 and (C60)3 (+)(CO2)1,2 are attributed to physisorption inside the "groove" of the dimer and the two "dimples" in the trimer cations of C60.Molecular dynamics simulations provide a qualitative assessment of the observed physisorption and a useful visualization of structural aspects.

ABSTRACT

Multiple attachment of CO2 to the monomer, dimer and trimer cations of C60 has been observed in the mass spectra of He nanodroplets sequentially doped with C60 and CO2 and exposed to electron ionization at 50 eV. Remarkable anomalies were seen in the ion yield for CO2 coverage for (C60)2 (+)(CO2)8 and (C60)3 (+)(CO2)1,2. These provide insight into the influence of steric properties on the nature of physisorption. The enhanced stabilities of (C60)2 (+)(CO2)8 and (C60)3 (+)(CO2)1,2 are attributed to physisorption inside the "groove" of the dimer and the two "dimples" in the trimer cations of C60. Molecular dynamics simulations provide a qualitative assessment of the observed physisorption and a useful visualization of structural aspects.
