Quasi-Classical Trajectory Dynamics Study on the Reaction of H with HO2
S. H. Mousavipour* and I. Yousefiasl
[Full Text PDF(J-STAGE)]
 | Quasi-classical trajectory simulations were carried out to study the dynamics of H + HO2 reaction on the lowest singlet potential energy surface. The effect of two potential wells due to the formation of water oxide (H2OO*) and hydrogen peroxide (HOOH*) on the kinetics of this system is investigated. The intramolecular vibrational energy redistribution involving excitation of the OH or OO bonds in HOOH is explored. |

Electronic Structure of Yttrium and Carbon Atoms Encapsulated Metallofullerenes, Y2C2@C82: Ultraviolet Photoelectron Spectroscopy and Theoretical Calculation
S. Hino,* T. Miyazaki, Y. Aoki, N. Wanita, M. Kato, R. Sumii, T. Akachi, T. Inoue, Y. Ito, T. Sugai, and H. Shinohara
[Full Text PDF(J-STAGE)]
Ultraviolet photoelectron spectra of three Y2C2@C82 isomers are almost identical at higher binding energy region, but differ drastically at the lower binding energy region near the Fermi level. The spectrum of C2v-Y2C2@C82 is well reproduced by simulation spectra obtained by ab initio calculation assuming a distorted Y2C2 tetragonal form in C2v C82 cage structure.

P.-J. Sung,* M.-R. Lin, M. Y. Chiang, and T.-L. Hwang
[Full Text PDF(J-STAGE)]
Five new briarane derivatives, briaexcavatins V–Z (1–5), were isolated from a cultured octocoral Briareum excavatum. The structures of compounds 1–5 were established by spectroscopic methods. Single-crystal X-ray diffraction data for 2 confirmed the structure. The relationships between 13C NMR chemical shifts and the conformations of the briaranes possessing an 11,12-epoxy group are described. Briarane 1 was found to show mild inhibitory effects on human neutrophil elastase release.

M. Haneda,* N. Aoki, K. Arimitsu, and H. Hamada
[Full Text PDF(J-STAGE)]
The catalytic activity of WO3-promoted Ir/SiO2 catalyst for NO reduction with CO is strongly dependent on the calcination conditions in the preparation process. WO3/Ir/SiO2 calcined at 1073 K in air was the highest active catalyst. Iridium species interacting strongly with WO3 were selectively created by high-temperature calcination, leading to higher activity.
