摘　　要：核磁共振技术(NMR)是迄今为止研究最完全、应用范围最广的波谱技术之一,遍及生物、医药、矿物勘探、化学等领域,多位杰出科学家因为NMR研究而获得诺贝尔奖,其中虞福春和他的同事普洛科特(W.G.Proctor)发现了核所处的化学环境会影响核的化学位移这一现象,也被称呼为Proctor-Yu(虞)效应。紧接着虞福春又在KSbF6的水溶液发现SbF6-的核磁共振谱线存在谱线劈裂现象,最终确认其是由于自旋耦合而产生。而这些重大成果在国内外教科书中鲜少提及。简述了虞福春的成长经历及其对于核磁共振发展的重大贡献。NMR is one of the most fully researched and widely used spectroscopy techniques so far,covering the fields of biology,medicine,mineral exploration,chemistry,etc.And many outstanding scientists have won the Nobel Award for their NMR research.Among them,Professor Yu Fu-Chun and his colleague Professor Proctor discovered that the chemical environment in which the nucleus is located affects the chemical displacement of the nucleus,which is also known as the Proctor-Yu effect.Immediately afterwards,Professor Yu Fu-Chun found that the NMR spectral lines of SbF_6~-ions were split in the aqueous solution of KSbF_6,and finally confirmed that it was caused by spin coupling.These major achievements are rarely mentioned in domestic and foreign textbooks.This paper briefly describes Professor Yu Fu-Chun's growth experience and Professor Yu Fu-Chun's significant contributions to the development of NMR.
