Research Abstract	1)個体表面における吸着反応、及び触媒機能の電子理論の展開(小林、舘脇)。数千個の点電荷がつくる靜電場に埋まれたLi^+_nF^-_<n-1>やLi^+_nF^-_<n+1>(n<15)クラスターのエネルギー状態を△SCF法で計算し、固体金属の状態密度を議論した。パラジウム結晶について、密度汎関数法で書かれたブロッホ関数でバンド構造の計算を行い、フェルミ準位、凝集エネルギー、格子定数及びバンドの分散関係を求めた。その結果、実験値や他の計算結果とほぼ一致する値が得られた。酸化マグネシウムを例にとり、イオン結晶での遠距離相互作用をとりいれる方法の検討も行った。 2)溶液内化学反応の動的過程に関する分子動力学論の展開(北浦、大峰、長嶋)。液体フッ化水素の熱力学的性質には、低温圧縮率が大きいことを除き、水のような異常性が見出されていない。両者の違いの原因を明らかにするため、液体HFについてモンテカルロシミュレーションを行い、分配関数から熱力学量を計算し、水素結合の効果を解析した。水クラスターと溶液のダイナミックス計算を行ない、ポテンシャルエネルギー面の構造とダイナミックス、また相転移との関係を明らかにした。静電緩和の解析から、液体の水とは違う1/fノイズ型の緩和現象を見出した。水和プロトンクラスターにおける分子間相互作用についての検討も行った。 3)高分子に特有の反応、及び高分子の成長反応の機構の分子軌道法理論の展開(今村、細矢)。Elongation法によって、非周期性高分子のいろいろなサイトにおける局所状態密度を計算する方法を確立した。直線上水素分子の配列した高分子系について適用し、abinitio計算の結果とよく合うことを確認した。グラファイトの電子構造に急速に収束するコロネンやピレンのトーラスネットワークのπ電子構造を計算し、その群論的な検討を行なった。
