Аннотация:
The atomic and electronic structure of some endo-, exo-, and endo-exohedral
complexes
of the fullerene C-60 with various guest atoms and molecules (He-n, H-2, and Li-2) are investigated using semiempirical and nonempirical quantum-chemical methods. The atomic core dynamics is studied by the method of molecular dynamics. It is shown that guest atoms and molecules in fullerene polyhedra acquire an orbital angular momentum due to the correlated motion of nuclei above the low-energy barriers of the potential surface within the carbon polyhedron even at low temperatures (from 4 to 78 K). The emergence of orbital angular momenta of nuclei of guest atoms and molecules is attributed to a change in the contribution of the orbital angular momentum of electrons to the potential surface of the
complexes
. The motion of Li ions in a polyhedron leads to blurring of the top of the valence band and to the emergence of a charge polarization wave in the carbon polyhedron. (C) 2000 MAIK "Nauka/Interperiodica".

Аннотация:
The results of ab initio Hartree-Fock calculations of endo- and exohedral C-60 fullerene
complexes
with the Li+ ion and Li-2 dimer are presented. The coordination of the Li+ ion and the Li-2 dimer in the endohedral
complexes
and the coordination of Li+ ion in the exohedral complex of C-60 fullerene are determined by the geometry optimization using the 3-21G basis set. In the endohedral Li+C60 complex, the Li+ ion is displaced from the center of the C-60 cage to the centers of carbon hexa- and pentagons by 0.12 nm. In the Li-2 dimer encapsulated inside the C-60 cage, the distance between the lithium atoms is 0.02 nm longer than that in the free molecule. The calculated total and partial one-electron densities of states of C-60 fullerene are in good agreement with the experimental photoelectron and X-ray emission spectra. Analysis of one-electron density of states of the endohedral Li+@C-60 complex indicates an ionic bonding between the Li atoms and the C-60 fullerene. In the Li+C60 and Li+@C-60
complexes
, there is a strong electrostatic interaction between the Li+ ion and the fullerene. (C) 2000 MAIK "Nauka/Interperiodica".

Аннотация:
The atomic and electron structures of toroidal carbon molecules (C-240 and two C-120 isomers) and related endohedral
complexes
with lithium (Li-2@C-n and Li-4@C-n) were theoretically studied using both nonempirical (3-21G basis set) and semiempirical (MNDO) calculation schemes. For the metal-containing compounds, the behavior of lithium atoms embedded into internal cavities of the carbon framework was studied using methods of molecular dynamics. It is demonstrated that the structure of electron levels of metal-containing carbon
complexes
exhibits an embedded state in the forbidden band, which appears due to the presence of electrons accepted from metal atoms. The position of this embedded state and the bandgap width depend both on the initial carbon structure and on the amount of metal atoms incorporated. (C) 2001 MAIK "Nauka/Interperiodica".

The electronic structures of all the possible isomers of endohedral and exohedral C(60) fullerene
complexes
with two lithium atoms are theoretically investigated. It is found that the electronic structures of these compounds are characterized by an impurity filled-level state determining the band gap. The location of the impurity state and, correspondingly, the band gap of the exohedral fullerene

depend on the coordination mode and the distance between the alkali metal ions. A similar dependence is observed for the total energy of the exohedral fullerene complex under investigation. (C) 2001 MAIK "Nauka/ Interperiodica".

Qualitative analysis of the products of plasmochemical synthesis of fullerenes with metallic nickel and cobalt has been carried out using electron paramagnetic resonance (EPR) and electron microscopy. These studies show that the synthesis products are mainly fullerenes, metallic nanoparticles coated with an insulating layer, and isolated atomic clusters. (C) 2001 MAIK "Nauka/Interperiodica".

Аннотация:
The mechanisms of inelastic scattering of low-energy protons with a kinetic energy of 2-7 eV by C6H6, C6F12, C-60, and C60F48 molecules are studied using the methods of quantum chemistry and nonempirical molecular dynamics. It is shown that, for the C6H6 + proton and C-60 + proton systems, starting from a distance of 6 angstrom from the carbon skeleton, the electronic charge transfer from the aromatic molecule to H+ occurs with a probability close to unity and transforms the H+ ion into a hydrogen atom and the neutral C6H6 and C-60 molecules into cation radicals. The mechanism of interaction of low-energy protons with C6F12 and C60F48 molecules has a substantially different character and can be considered qualitatively as the interaction between a neutral molecule and a point charge. The Coulomb perturbation of the system arising from the interaction of the noncompensated proton charge with the Mulliken charges of fluorine atoms results in an inversion of the energies of the electronic states localized, on the one hand, on the positively charged hydrogen ion and, on the other hand, on the C6F12 and C60F48 molecules. As a result, the neutral molecule + proton state becomes the ground state. In turn, this inversion makes the electronic charge transfer energetically unfavorable. Quantum-chemical and molecular-dynamics calculations on different levels of theory showed that, for fluorine derivatives of some aromatic structures (C6F12, C60F48), the barriers to proton penetration through carbon hexagons are two to four times lower than for the corresponding parent systems (C6H6, C-60). This effect is explained by the absence of active pi-electrons in the case of fluorinated molecules.

Аннотация:
We report g tensors of surface color centers, so-called F-s(+) centers, of MgO calculated with two density-functional approaches using accurately embedded cluster models. In line with recent UHV measurements on single-crystalline MgO film, we determined only small g-tensor anisotropies and negative shifts Delta g equivalent to g-g(e) for all F-s(+) sites considered, namely, (001)-terrace, step, edge, and corner sites. The g values are very sensitive to the local structure of the defect: relaxation reverses the sign of Delta g. However, accounting for the spin-orbit interaction either self-consistently or perturbatively yields very similar results. In addition to the values of the tensor components, their direction with respect to the surface was determined. In contrast to edges, significant deviations from ideal C-2v symmetry were found for F-s(+) centers at steps. Recent data on single-crystalline thin films are reevaluated in the light of these results. (c) 2006 American Institute of Physics.
