 note = {application/pdf, 論文(Article), The K-band electron paramagnetic resonance due to the photoinduced midgap state has been measured in an M-X chain complex [Pt(en)2 ][Pt(en)2Cl2](ClO4)4,(en)=ethylenediamine, at 77 K. The angular variations of the spectral line shape and the intensity show that the photoinduced unpaired electron is localized on the segment Pt-Cl-Pt of the M-X chain bonds. The pσ orbit of the intervening Cl- ion is found to share 30–40 % of the density of the unpaired electron, based on the following hyperfine constants of the constituent 195Pt and 35,37Cl nuclei: A∥Pt=378×10-4 cm-1 and A∥Cl=55×10-4 cm-1 for the quantization direction parallel to the chain axis; A⊥Pt=375×10-4 cm-1 and A⊥Cl<5×10-4 cm-1 for the direction perpendicular to the chain axis. The present result supports the notion that the photoinduced state is the spin soliton of two-site-type propagating along the M-X chain bonds. The possibility of the polaron is clearly excluded., M-X鎖錯体[Pt(en)2][Pt(en)2Cl2](ClO4)4に光誘起されるミッドギャップ状態の不対電子の分布形態を、Kバンドのマイクロ波を用いた電子常磁性共鳴で観察調査した。磁場方位依存性の結果より、不対電子はPt-Cl-Ptの部分に局在していることが明らかとなった。195Pt核と35,37Cl核の超微細構造定数の実験値より、不対電子は2個の195Pt核のd-軌道と1個の35,37Cl核のp-軌道の上にほぼ均等に分布していることが示される。これにより、光誘起ミッドギャップ状態がスピンソリトンであることが明確となった。, http://link.aps.org/abstract/PRB/v48/p4245},
