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.

Аннотация: Calculations for a one-dimensional model of RF heating of a cylindrical graphite conductor have been carried out. The heating dynamics are analyzed in the general form. Conductor temperature profiles and the times for heating up to the graphite sublimation temperature as a function of current and frequency have been obtained. A model of conductor heating with partial return of the energy irradiated by the conductor surface has been considered. Frequency and current ranges have been determined to carry out this graphite sublimation method in a chamber with reflecting walls. The problem is associated with carbon vapor production and subsequent synthesis of fullerenes and other carbon structures. (C) 2000 MAIK "Nauka/ Interperiodica".

Аннотация: A new scheme of fullerene formation is proposed on the basis of the similarity between the experimentally detected carbon structures. According to experimental data, the microclusters of C(2) and C(10) are synthesized first and then either an intermediate nucleus cluster or an obtainable lower fullerene is assembled from them. A high-symmetry fullerene can be assembled with a high probability from a nucleus cluster with a "good" symmetry. The atomic and electronic structures of molecules such as C(36), C(60), C(70), and C(76) are analyzed. For C(36), the NMR spectra are calculated and compared with the experimental data.

Аннотация: 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".

Заглавие : Electron density as the main parameter influencing the formation of fullerenes in a carbon plasma
Место публикации : Phys. Solid State: AMER INST PHYSICS, 2002. - Vol. 44: 5th International Workshop on Fullerence and Atomic Clusters (JUL 02-06, 2001, ST PETERSBURG, RUSSIA), Is. 3. - P419-423. - ISSN 1063-7834, DOI 10.1134/1.1462659

Аннотация: Thermodynamic estimates are presented for the formation of spheroidal and flat carbon clusters from reactant species of different charges. Charge is shown to strongly influence the geometry and stability of flat clusters. Changes in the charge of flat clusters can promote both their folding to spheroidal structures and their dissociation. It is concluded that the fluctuations of electron concentration in carbon plasmas can result in the accumulation of fullerene clusters and the dissociation of flat clusters.

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: Fullerenes containing manganese and iron atoms are synthesized in a high-frequency carbon-helium plasma at atmospheric pressure. The electron paramagnetic resonance (EPR) spectrum of the synthesized compound contains not only lines attributed to iron atoms but also the lines of a manganese ion pair with an additional hyperfine structure. The latter lines are assigned to the endohedral complex Mn-2@C-n (n 70). The possible existence of these structures is evaluated from quantum-chemical calculations of the optimum geometry of the endohedral fullerene Mn-2@C-84 with C-2V symmetry. It is found that the manganese atoms are spaced similar to 2.72 angstrom apart at the center of the molecule.
