Journal ArticleDOI
Core hole effect in NEXAFS spectroscopy of polycyclic aromatic hydrocarbons: Benzene, chrysene, perylene, and coronene
Hiroshi Oji,Ryuichi Mitsumoto,Eisuke Ito,Hisao Ishii,Yukio Ouchi,Kazuhiko Seki,Toshihiko Yokoyama,Toshiaki Ohta,Nobuhiro Kosugi +8 more
TL;DR: In this article, the core-hole effect in benzene was analyzed and it was found that the magnitude of the core hole effect is strongly dependent on the combination of the excited site and final vacant orbital.
Journal ArticleDOI
Electronic Structures and Chemical Bonding of Fluorinated Fullerenes Studied by NEXAFS, UPS, and Vacuum-UV Absorption Spectroscopies
Ryuichi Mitsumoto,Tohru Araki,Eisuke Ito,Yukio Ouchi,Kazuhiko Seki,Koichi Kikuchi,Yohji Achiba,Hiroshi Kurosaki,Takaaki Sonoda,Hiroshi Kobayashi,Olga V. Boltalina,Valeria K. Pavlovich,Lev N. Sidorov,Yoshiyuki Hattori,Ning Liu,Sumitoshi Yajima,Shinji Kawasaki,Fujio Okino,Hidekazu Touhara +18 more
TL;DR: In this article, the chemical bonding and the electronic structures of C60Fx and C70Fx were investigated by near edge X-ray absorption fine structure (NEXAFS) spectroscopy and UV photoemission (UPS), which are useful methods for examining the unoccupied and the occupied states, respectively.
Journal ArticleDOI
Polarized nexafs spectroscopic studies of poly(butylene terephthalate), poly(ethylene terephthalate), and their model compounds
Toshihiro Okajima,Kazuyoshi Teramoto,Ryuichi Mitsumoto,Hiroshi Oji,Yasushi Yamamoto,Ikuko Mori,Hisao Ishii,Yukio Ouchi,Kazuhiko Seki +8 more
TL;DR: In this article, the polarization dependence of the NEXAFS spectra of oriented small analogous molecules is used for the assignment of the near edge X-ray absorption fine structure of polymers.
Journal ArticleDOI
Surface analysis of CVD carbon using NEXAFS, XPS and TEM
J. Kikuma,K. Yoneyama,M. Nomura,T. Konishi,T. Hashimoto,Ryuichi Mitsumoto,Y. Ohuchi,Kanako Seki +7 more
TL;DR: In this article, the surface concentration of C C double bonds of carbon thin films produced by chemical vapor deposition (CVD) of hydrocarbon gases onto a hard carbon substrate has been analyzed using various surface analytical techniques.
Journal ArticleDOI
Fluorination of fullerene C60 and electrochemical properties of C60Fx
TL;DR: In this paper, the electronic structure changes of C 60 upon fluorination were also investigated by XANES and UPS Three stepwise reversible reduction peaks (250, 215 and 185 V), and an irreversible reduction peak (28-32 V) corresponding to CF reduction were observed on the cyclic voltammograms.
