This environment proved so stimulating that one year was extended to twelve, and the young family grew up as Californians; three children have now settled on the West Coast.

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

Freeman took statutory retirement in 1999, but continued his research with a long-time colleague Eriks Kupce, and produced his third book, "NMR in
Chemistry and Medicine", published in 2003, and later translated into Russian.

With his research students at Oxford, several publications on new NMR techniques were produced, including work on two-dimensional NMR. Freeman acknowledged that part of this work was triggered by the seminal suggestion of

Along with research at Varian on double-resonance, double-quantum effects, spin-lattice relaxation, and
Fourier transformation, Freeman assisted in the development of new Varian NMR spectrometers (XL-100 and CFT-20).
