I thought that what we should do is develop some of the more difficult compounds... elements. Iron in the group of the periodic table has the next element beneath it, ruthenium, so that was one. Ruthenium-99 was not an easy one, both in making the sources of the radiation and in doing it at very low temperatures, and also the physics group at the Technische Hochschule in Munich, Mössbauer’s group were working in that area as well and as far as the physics of the technique were concerned they were clearly in much better shape than I would ever be to do this. But we knew the chemical aspects of it well and many of the compounds of ruthenium that we studied gave us some interesting information and I think we also found out for the first time the quadrupole moment of the ruthenium nucleus.
Norman Greenwood (1925-2012) was born in Australia and graduated from Melbourne University before going to Cambridge. His wide-ranging research in inorganic and structural chemistry made major advances in the chemistry of boron hydrides and other main-group element compounds. He also pioneered the application of Mössbauer spectroscopy to problems in chemistry. He was a prolific writer and inspirational lecturer on chemical and educational themes, and held numerous visiting professorships throughout the world.
