| Citation | Dr Freeman has been particularly concerned with the development of High Resolution Nuclear Magnetic Resonance since 1956. Over the years he has initiated very many of the techniques of high resolution Nuclear Magnetic Resonance which are now used routinely all over the world. He was responsible for the exploitation of double and triple resonance techniques for the analysis of high resolution NMR spectra and for the determination of relative signs of spin coupling constants in proton spectra. His two major papers on the theory of double resonance and on the theory of spin tickling form the basis of methods used universally today. He showed how C-13 and other weak resonances could be observed indirectly by double resonance methods and also demonstrated the use of double quantum transitions for the assignment of NMR spectra. He then published a series of elegant papers on spin-spin and spin-lattice relaxation in high resolution spectra, demonstrated some of the earliest uses of Fourier transform spectroscopy, and pioneered the methods of measuring spin-lattice relaxation times of C-13 spectra and their use for structural purposes. Dr Freeman's work is characterised by novelty and ingenuity expressed with economy and style. |
