British physical chemist. After graduating from the University of Leeds, he served as a radar officer during World War II. After the war, he joined the laboratory of RGW Norrish at Cambridge University, where he succeeded in making a large-capacity flash discharge tube. In 1949-1950, he published a new flash photolysis method using this to measure short-lived intermediate molecular species (free radicals, triplet excited molecules, etc.). In the following years, he published groundbreaking research, including the measurement of free radicals such as C 2 , CH , CN, and OH in the explosion of acetylene-oxygen mixtures, the measurement of the recombination reaction rate constant of iodine molecules in rare gases, and the measurement of the triplet excited state of anthracene in solution. In 1955, he became a professor at the University of Sheffield. He has also conducted many other important research projects, including the study of the triplet excited state of benzophenone and the measurement of benzyl free radicals produced by photo- and radiolysis in rigid solvents. In 1967, he shared the Nobel Prize in Chemistry with Norrish. Porter Porter |
イギリスの物理化学者.リーズ大学卒業後,第二次世界大戦中はレーダー部隊の士官として勤務.戦後ケンブリッジ大学のR.G.W. Norrish(ノリッシュ)の研究室に入り,大容量のせん光放電管の製作に成功し,1949~1950年これを用いて短寿命中間分子種(遊離基,三重項励起分子など)を測定する新しいせん光光分解法を発表した.続く数年間にアセチレン-酸素混合物の爆発における C2,CH,CN,OHなどの遊離基の測定,希ガス中におけるヨウ素分子の再結合反応速度定数の測定,溶液中におけるアントラセンの三重項励起状態の測定など,画期的な研究を発表した.1955年以降シェフィールド大学教授となる.ほかにもベンゾフェノンの三重項励起状態の研究,剛性溶媒中に光および放射線分解で生成したベンジル遊離基の測定など多くの重要な研究がある.1967年Norrishとともにノーベル化学賞を受賞した. ポーター
