Research Abstract	1.量子化学基礎理論の精密化と再構築:シュレーディンガー方程式の解である正確な波動関数の構造について研究を行った。励起状態の正確な波動関数を求める方法として、ICI-CI法およびECC-CI法を定式化し、多くの励起状態を一挙に計算できる方法を開発した。逆(inverse)ハミルトニアンを用いて定義される逆シュレーディンガー方程式が、シュレーディンガー方程式と等価であり、変分原理を満たすことを示した。逆ハミルトニアンを用いてICI法を一般化し、正確な解を与える解法を提案した。 2.ファインなスペクトロスコピーと反応の量子ダイナミクス:ポテンシャル曲線の不連続を解消する方法を開発し、励起状態やイオン化状態の分光定数の理論計算に応用した。多電子過程を精密に記述するSAC・CI general-R法を用いて、価電子イオン化状態や内殻励起・イオン化状態を高い精度で計算し、精密な帰属を与えた。Dirac-Fock法や擬相対論に基づく電子相関理論を、多体摂動法や結合クラスター法で実現した。X^-,XO_4^-(X=F,Cl,Br,I)のX核磁気遮蔽定数やSe,Te,Sn,Pb等の重原子核の磁気遮蔽定数の理論研究を行い、相対論と電子相関の効果を同時に考慮することの重要性を示した。精密な量子動力学法によって、H_3の2S状態の前期解離過程を研究した。また、H_2COの全自由度のポテンシャルを決定し、解離反応の速度定数や反応のモード選択性を解明した。 3.巨大系に共通する電子状態理論:QM/MM法を用いて、光合成反応中心の電子移動とプロトン移動のカップリングのメカニズムについて、反応に伴う構造緩和と蛋白が色素の電子状態に及ぼす影響について研究した。 4.生体反応系の電子論とダイナミクスの解明:人工光合成系や分子素子への応用が期待される2種類のポルフィリン二量体について、SAC-CI法により励起状態を研究した。複雑な吸収スペクトルの帰属に成功し、二量化による電子構造の変化を明らかにした。緑色蛍光蛋白色素(GFPC)とそのミュータントの吸収スペクトル、蛍光スペクトルを帰属し、実在する分子を特定した。Fe(III)ポルフィリンシアン化物の電子状態をSAC-CI法で研究した。励起状態も含めて、常磁性化学シフトの挙動がスピン伝達機構により合理的に説明できることを示した。 5.凝縮系における反応の電子論とダイナミクス:極性媒質の反応場下におけるダイナミクスを取り扱う新しい理論的方法を開発し、水分子やN-メチルアセトアミド分子のIRやRamanスペクトルに応用した。 6.遷移金属錯体の構造と触媒反応のメカニズム:二酸化炭素水素化反応およびアルケンのヒドロシリル化反応の反応機構と中心金属の電子状態との関連を明らかにした。また、金属フタロシアニンの構造と物性の関連性を電子配置から明らかにした。
