Research Abstract	・動的構造追跡用表面和周波発生(SFG)システムの構築 (a)355nm(YAGの三倍波)の光を励起光とするポンプラインを増設し、〜20psの時間分解能での動的分子構造追跡システムへと展開した。 (b)ブロードバンドSFGシステムの構築より高度なシステムとして100fs程度のパルス幅のレーザーをベースとするブロードバンドSFGシステムの構築を目指して、既有のフェムト秒可視光ポンプ-赤外光プローブ装置の増幅システムの改良を行い、可視光で2倍、赤外光で3倍の強度が得られた。また、SFGシステム増設のための設計を行った。・SFG測定の電気化学システムへの適用 2種類の電気化学SFG分光測定セルを設計・製作した。また、水晶プリズム上に作成した金属薄膜電極と水溶液界面での水を可視、赤外光の照射と出射SFGの測定をプリズム側から行うことにより、検出に成功した。電位による水のOH伸縮振動強度の変化が明確に観測できた。・ダイナミクス測定用試料の調製光励起ダイナミクス測定のための酸化チタン薄膜の水晶プリズム上への作製過程をSFGにより追跡した。
