Reference excerpt

Geoffrey Bodenhausen (born 1951) is a French chemist specializing in nuclear magnetic resonance, being highly cited in his field. He is a Corresponding member of the Royal Netherlands Academy of Arts and Sciences and a Fellow of the American Physical Society. He is professeur émérite at the Department of Chemistry at the École Normale Supérieure (ENS) in Paris and professeur honoraire at the Laboratory of Biomolecular Magnetic Resonance of the École Polytechnique Fédérale de Lausanne (EPFL). He is a member of the editorial board of the journal Progress in Nuclear Magnetic Resonance Spectroscopy. He is the chair of the editorial board of the journal Magnetic Resonance.

Education He received a Diploma in chemistry from ETH Zurich in 1974, and a D.Phil. from Oxford University in 1977, supervised by Ray Freeman.

Career Bodenhausen began his post-doctoral research under the supervision of Robert and Regitze Vold at the University of California, San Diego. He subsequently worked as Research Staff with Leo Neuringer and Robert G. Griffin at the Massachusetts Institute of Technology and then in 1980 he moved to the ETH in Zurich, where he joined the group of Richard R. Ernst. In 1985 he was appointed to a professorship at the University of Lausanne. In 1994 he became a professor at the Florida State University in Tallahassee filling the position of Director of the Institute for Advanced Studies in Magnetic Resonance. In 1996 he was elected fellow of the American Physical Society "for his numerous contributions toward making magnetic resonance one of the most sophisticated and versatile methods available for gaining insight into structure and dynamics of molecules in condensed and gas phase." In 1996 he was awarded a professorship at the Ecole Normale Supérieure in Paris. He also held a part-time position at the University of Lausanne, and, after 2001, at the École Polytechnique Fédérale de Lausanne. From 2005 to 2011 he chaired the Board of Trustees of EUROMAR.

Research Bodenhausen was one of the pioneers in the field of two-dimensional Fourier transform NMR spectroscopy. In the group of Ray Freeman he contributed to some of the first heteronuclear experiments. In 1976 he contributed to a scheme to induce selective excitation of small portions of multiline spectra, later named DANTE by Morris and Freeman. He also analysed spin-echo spectra and rationalized the appearance of negative lines. He developed the first phase-cycle known as 'Exorcycle'. In 1977 Bodenhausen and Freeman illustrated that it was possible to observe a spectrum of a heteronucleus (an atomic nucleus other than a proton) to achieve indirect detection of the proton resonance frequencies, and the correlations of chemical shifts between protons and heteronuclei. In 1980 Bodenhausen and D. J. Ruben introduced the HSQC (Heteronuclear Single Quantum Coherence) experiment, which produces sensitive two-dimensional (2D) spectra with one axis for protons (1H) and the other for a heteronucleus, usually 13C or 15N. This double INEPT has been the base for many subsequent heteronuclear correlation experiments published in the literature and it has proven pivotal in the spectroscopy of organic chemistry and in the field of protein NMR. One of the first steps in increasing the information content of NMR spectra was the introduction of a relayed coherence transfer by Geoffrey Bodenhausen together with Philip Bolton and Gerhard Eich. In 1984 he published with Herbert Kogler and Richard R. Ernst a pivotal article in the Journal of Magnetic Resonance where they described how to design phase cycles allowing the selection of specific coherence-transfer pathways in NMR pulse experiments. In 1987 he published with Richard R. Ernst and Alexander Wokaun Principles of Nuclear Magnetic Resonance in One and Two Dimensions, considered a classical monograph on the topic of multidimensional NMR.

Worked examples

Example 1 — a first encounter with Geoffrey Bodenhausen

Start with the simplest possible case. Write down what Geoffrey Bodenhausen claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In chemistry, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Geoffrey Bodenhausen before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Geoffrey Bodenhausen ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Geoffrey Bodenhausen

In research: Geoffrey Bodenhausen appears in chemistry research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Geoffrey Bodenhausen in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Geoffrey Bodenhausen is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1951 births, 20th-century French chemists, 21st-century French chemists, so understanding it makes those chapters shorter.
In everyday life: Look for Geoffrey Bodenhausen outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
