Born August 14, 1933, Winterthur, Switzerland Swiss chemist. Graduated from the Chemistry Department of the Swiss Federal Institute of Technology in Zurich in 1956, and obtained his PhD in physical chemistry from the same university in 1962. After serving as a researcher at the Varian Society in Palo Alto, California, USA from 1963 to 1968, he returned to Switzerland and became a lecturer at his alma mater, becoming an associate professor in 1970 and a professor in 1976. During his research in the USA, he discovered a method to dramatically improve the accuracy of high-resolution nuclear magnetic resonance (NMR) analysis. In other words, he changed the conventional method of slowly changing the wavelength of electromagnetic waves to a method of instantly applying a strong pulsed electromagnetic wave, and then obtained an absorption spectrum by applying a Fourier transform to the signal emitted by the sample. This discovery expanded the range of objects that could be analyzed. Furthermore, since the late 1970s, he has expanded NMR to three and four dimensions, making it possible to apply it to various fields such as biochemistry, medicine, biology, and condensed matter physics. In 1991, he was awarded the Nobel Prize in Chemistry. Ernst |
[生]1933.8.14. スイス,ウィンタートゥール スイスの化学者。 1956年チューリヒのスイス連邦工科大学化学科を卒業,62年同大学で物理化学博士号を取得。 63~68年アメリカ,カリフォルニア州パロアルトのバリアン協会研究員を経て,スイスに戻り,母校で講師となり,70年助教授,76年教授に就任。アメリカでの研究時代に,高分解能核磁気共鳴 (NMR) 分析法の精度を飛躍的に高める方法を発見した。すなわち従来の電磁波の波長をゆっくりと変化させる方法を,強力なパルス状の電磁波を瞬時にかける方法に変え,さらに試料が発する信号にフーリエ変換を施して吸収スペクトルを得るのである。この発見により分析可能な対象が広がった。さらに 1970年代後半以降は NMRを3次元,4次元にまで拡張し,生化学,医学,生物学,物性物理学などさまざまな分野での応用を可能にした。 91年ノーベル化学賞を受賞。 エルンスト
