A. David Buckingham

Life and career

David Buckingham obtained a Bachelor of Science and Master of Science, under Professor Raymond Le Fevre, from the University of Sydney and a PhD from the University of Cambridge supervised by John Pople. He was an 1851 Exhibition Senior Student in the Physical Chemistry Laboratory at the University of Oxford from 1955 to 1957, Lecturer and then Student (Fellow) at Christ Church, Oxford from 1955 to 1965 and University Lecturer in the Inorganic Chemistry Laboratory from 1958 to 1965. He was Professor of Theoretical Chemistry at the University of Bristol from 1965 to 1969. He was appointed Professor of Chemistry at the University of Cambridge in 1969.He was elected a Fellow of the Royal Society in 1975, a Fellow of the American Physical Society in 1986 and a Foreign Associate of the United States National Academy of Sciences in 1992. He was a member of the International Academy of Quantum Molecular Science. Buckingham was elected to the Australian Academy of Science in 2008 as a Correspo

Scientific contributions

Professor Buckingham's research has focussed on the measurement and understanding of the electric, magnetic and optical properties of molecules; as well as on the theory of intermolecular forces.Initially he worked on dielectric properties of liquids, such as dipole moments of molecules in both solution and gas phases. He developed the theory of the interaction of molecules in liquids and gases with external electric and magnetic fields. In 1959, he proposed a direct method of measurement of molecular quadrupole moments of molecules (measured in buckinghams), which he demonstrated experimentally in 1963 on the carbon dioxide molecule. In 1960, he developed theories of solvent effects on nuclear magnetic resonance (NMR) spectra and vibrational spectra of molecules. In 1962 he considered the effect on NMR spectra of molecular orientation in a strong electric field, and developed a method to determine the absolute sign of the spin-spin coupling constant. In 1968, he determined the first a

Personal life

In July 1964, David Buckingham sailed from Southampton to Montréal, to take up a research post in Ottawa. On the voyage he met Jillian Bowles, a physiotherapist who was heading to a post in BritishColumbia. They were engaged in January 1965 and married at Christ Church Cathedral, Oxford six months later. They were married for over 55 years, and had three children: Lucy Elliot and Mark Vincent, born in Bristol, and Alice Susan born in Cambridge. Between them they had eight grandchildren: Carola, Peter, Oliver, William, Patrick, Anna, Samuel and Maeve.David Buckingham died in Cambridge on 4 February 2021, seven days after his 91st birthday; he was survived by Jill, their children and grandchildren.
