瑞典皇家科学院将1991年诺贝尔化学奖授予瑞士物理化学家理查德·R·恩斯特,以表彰他在发展高分辨核磁共振波谱学方面所作出的杰出贡献。1966年恩斯特与美国同事研制出脉冲傅利叶变换核磁共振谱仪(EINMR),发现用短促的强脉冲取代核磁共振谱管用的缓慢扫描无线电波,能显著提高核磁共振的灵敏度,他的敏锐发现使核磁共振技术能用于分析更多种类的核和数量较少的物质。1968年他开始在苏黎世联
The Royal Swedish Academy of Sciences awarded the 1991 Nobel Prize in Chemistry to Swiss physicist Richard R. Ernst for his outstanding contribution to the development of high-resolution NMR spectroscopy. In 1966, Ernst and his colleagues in the United States developed a pulse Fourier Transform Nuclear Magnetic Resonance Spectrometer (EINMR) and found that using a short burst of intense pulses to replace the slow-scan radio waves used in nuclear magnetic resonance spectroscopy can significantly improve the sensitivity of nuclear magnetic resonance. His sharp discovery Enable the use of nuclear magnetic resonance technology for the analysis of a greater variety of nuclei and a smaller number of substances. In 1968 he started in Zurich United
