Norman Sheppard

Professor Norman Sheppard FRS

Fellow


Elected: 1967

Biography

Norman Sheppard was well known for his contributions to infrared and Raman spectroscopy, and to nuclear magnetic resonance (NMR). He published numerous papers on the relation between the infrared spectra and structure of a wide range of molecules, for example, phthiocerane, puberulic and puberulonic acids, the H3O+ ion, afwillite and the triphenylmethyl cation. His work on hydrocarbons was especially noteworthy in establishing clearly the existence of rotational isomers. In the field of NMR, he was the first to make use of the carbon-13 isotope to elucidate the spin coupling between equivalent hydrogen atoms. He also applied NMR successfully to problems of internal rotation and to the structure of gibberellic acid.
