Abstract

The isotope effect induced by deuterium substituted species is observed in molecular properties, such as geometry, kinetics, and electronic state, of the molecules through nuclear-electron interaction. Theoretical considerations and experimental alignments have been studied by ab initio molecular orbital, density functional theory, and other empirical strategies. The Born-Oppenheimer approximation with nuclear vibrational wavefunction can treat isotope effect because nuclear mass effect account for the average istance of vibrational motion. In this study, we introduce Morse anharmonic oscillator model to calculate average internuclear distance of diatomic molecules having X-H bonding and X-D bonding. Morse parameters are determined by fitting to potential energy surface of molecular orbital and/or density functional calculations, and then the average distance are obtained as the expectation value of the analytical Morse vibrational wavefunction. Nuclear magnetic resonance shielding constants of the H/D isotopomer are calculated again on the average distance by using GIAO with B3LYP and CCSD calculation. © 2010 Wiley Periodicals, Inc., 研究者情報DB

38. II.1 Magnesium diboride and the two-band scenario.

Author

Scharnberg, Kurt, Kruchinin, Sergei, Kawabe, Hiroyuki, Nagao, Hidemi, and Kruchinin, Sergei P.

Abstract

We investigate two-band superconductivity in ultrasmall grain. The Richardson's exact solution is extended to two-band systems, and a new coupled equation is derived according to the procedure of Richardson's works. Parity gap and condensation energy of ultrasmall two-band superconducting grain are numerically obtained by solving the coupled equations. We discuss these properties in ultrasmall grain in relation to the correlation, interband interaction, and size dependence. [ABSTRACT FROM AUTHOR]

47. ESR Spectra of Benzene Anion

Author

Kimura, Minoru, Kawabe, Hiroyuki, Nishikawa, Kiyoshi, and Aono, Shigeyuki

Abstract

Based on the spin density calculated in our previous paper, the ESR spectra of the benzene anion (exactly the dihydrophenylide ion) are analyzed by the Bloch equation. A hyperfine spectrum broader than those of usual aromatic radicals attributes to the chemical exchange process that the ion in question surrounded by solvent molecules undergoes a rotational motion characterized by the time τ which is the life time of chemical exchange. The line shape for each hyperfine spectrum is given in terms of 1⁄T2and τ under the condition of τ⁄T2<<1.

48. Possibility of Superconducting and Other Phases in Organic High Polymers of Polyacene Carbon Skeletons. II. Screened Electron–Electron Interaction —Method of Renormalization Group—

Author

Kimura, Minoru, Kawabe, Hiroyuki, Nishikawa, Kiyoshi, and Aono, Shigeyuki

Abstract

The electron–electron interaction which is crucial in determining whether new phases will arise or not in polyacene is investigated by means of the renormalization group. This approach is valuable to effectively include, from the view-point of the group theory, the higher order diagrams not taken into account in the random phase approximation of the previous work. It is found that there is a range of coupling constants where the singlet superconducting phase without simultaneous CDW ordering can be expected.

49. Possibility of Superconducting and Other Phases in Organic High Polymers of Polyacene Carbon Skeletons. I. Screened Electron–Electron Interaction—Random Phase Approximation—

Author

Kimura, Minoru, Kawabe, Hiroyuki, Nakajima, Akihiko, Nishikawa, Kiyoshi, and Aono, Shigeyuki

Abstract

The effective electron–electron interaction in the high polymers of polyacene carbon skeleton is investigated. The appearance of various phases in this system depends on associated parameters characterizing the electron–electron interactions near the Fermi level. The main purpose of this work is to estimate these parameters under the random phase approximation and to presume whether this polymer may or may not be superconductor at room temperature.

50. Magnetic circular dichroism of excitons in KI and RbI

Author

Koide, Tsuneharu, Kawabe, Hiroyuki, Shidara, Tetsuo, Miyauchi, Hiroshi, Nakajima, Nobuo, Iio, Katsunori, and Fukutani, Hirohito

Abstract

The magnetic circular dichroism spectra of KI and RbI have been measured with the reflection method at 30 K as well as at room temperature in the energy region from 5 to 9.5 eV. Accurate effective g values (g eff ) of excitons were determined on the basis of the rigid-shift model. The relation between the obtained values of g eff and the band structure is discussed in terms of the tight-binding model.
