Journal ArticleDOI
The dipolar endofullerene HF@C60
Andrea Krachmalnicoff,Richard Bounds,Salvatore Mamone,Shamim Alom,Maria Concistrè,Benno Meier,Karel Kouřil,Mark E. Light,Mark R. Johnson,Stéphane Rols,Anthony J. Horsewill,A. Shugai,Urmas Nagel,Toomas Rõõm,Marina Carravetta,Malcolm H. Levitt,Richard J. Whitby +16 more
TL;DR: The encapsulation of hydrogen fluoride inside C60 is reported using molecular surgery to give the endohedral fullerene HF@C60, which exhibits quantization of its translational and rotational degrees of freedom, as revealed by inelastic neutron scattering and infrared spectroscopy.
Journal ArticleDOI
Long-lived nuclear spin states in methyl groups and quantum-rotor-induced polarization.
Benno Meier,Jean-Nicolas Dumez,Gabriele Stevanato,Joseph T. Hill-Cousins,Soumya Singha Roy,Pär Håkansson,Salvatore Mamone,Richard C. D. Brown,Giuseppe Pileio,Malcolm H. Levitt +9 more
TL;DR: Following dissolution, cross-relaxation of the hyperpolarized LLS, induced by heteronuclear dipolar couplings, generates strongly enhanced antiphase NMR signals, which explains the NMR signal enhancements observed for (13)C-γ-picoline.
Journal ArticleDOI
Nuclear spin conversion of water inside fullerene cages detected by low-temperature nuclear magnetic resonance.
Salvatore Mamone,Maria Concistrè,Elisa Carignani,Benno Meier,Andrea Krachmalnicoff,Ole G. Johannessen,Xuegong Lei,Yongjun Li,Mark Denning,Marina Carravetta,Kelvin S. K. Goh,Anthony J. Horsewill,Richard J. Whitby,Malcolm H. Levitt +13 more
TL;DR: Numerical simulations suggest the simultaneous presence of a spin diffusion process allowing neighbouring ortho and para molecules to exchange their angular momenta in the water-endofullerene H2O@C60 system.
Journal ArticleDOI
Electrical detection of ortho-para conversion in fullerene-encapsulated water.
Benno Meier,Salvatore Mamone,Maria Concistrè,Javier Alonso-Valdesueiro,Andrea Krachmalnicoff,Richard J. Whitby,Malcolm H. Levitt +6 more
TL;DR: It is shown that the bulk dielectric constant of this substance depends on the ortho/para ratio, and changes slowly in time after a sudden temperature jump, due to nuclear spin conversion.
Journal ArticleDOI
Theory of long-lived nuclear spin states in methyl groups and quantum-rotor induced polarisation
Jean-Nicolas Dumez,Jean-Nicolas Dumez,Pär Håkansson,Salvatore Mamone,Benno Meier,Gabriele Stevanato,Joseph T. Hill-Cousins,Soumya Singha Roy,Richard C. D. Brown,Giuseppe Pileio,Malcolm H. Levitt +10 more
TL;DR: The formalism for describing the behaviour of long-lived nuclear spin states in methyl groups is expanded, with special attention to the hyperpolarisation effects observed in (13)CH3 groups upon rapidly converting a material with low-barrier methyl rotation from the cryogenic solid state to a room-temperature solution.
