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
Quantum rotation of ortho and para-water encapsulated in a fullerene cage
C. Beduz,Marina Carravetta,Judy Y.-C. Chen,Maria Concistrè,Mark Denning,Michael Frunzi,Anthony J. Horsewill,Ole G. Johannessen,Ronald G. Lawler,Xuegong Lei,Malcolm H. Levitt,Yongjun Li,Salvatore Mamone,Yasujiro Murata,Urmas Nagel,Tomoko Nishida,Jacques Ollivier,Stéphane Rols,Toomas Rõõm,Riddhiman Sarkar,Nicholas J. Turro,Yifeng Yang +21 more
TL;DR: Investigation of the quantized rotation and ortho–para conversion of single water molecules trapped inside closed fullerene cages reveals that the ground state of encapsulated ortho water has a lifted degeneracy, associated with symmetry-breaking of the water environment.
Journal ArticleDOI
Long-lived nuclear spin states in the solution NMR of four-spin systems.
TL;DR: The existence of long-lived nuclear spin states in four-spin systems is explored by solution-state NMR experiments and it is proved to exist in three different natural product molecules, each containing either a AA'BB' or aAA'XX' proton spin system.
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.
