Summary
Jean Louis Charles Jeener (31 July 1931 – 10 June 2023) was a Belgian physical chemist and physicist, well known for his experimental and theoretical contributions to spin thermodynamics in solids and for his invention of Two-dimensional nuclear magnetic resonance spectroscopy. He was born in Brussels on 31 July 1931, son of biologist Raymond Jeener and Hélène Massar. He was married to Françoise Henin. Jenner died on 10 June 2023, at the age of 91.[1]

Early life edit
Jeener grew up in Brussels.
Career edit
Jeener was professor in Physics at Université Libre de Bruxelles (ULB) from 1960 until he retired in 1996.
At ULB, Jeener researched spin thermodynamics and spin dynamics in solids. He introduced the “Jeener-Broekaert sequence” for creating observable quantities of dipolar order in solids.[2]
Nuclear magnetic resonance spectroscopy edit
Jeener is best known for introducing two-dimensional NMR spectroscopy (2DNMR). In a lecture at the AMPERE Summer School in Basko Polje, Yugoslavia, September 1971,[3][4] he proposed a novel technique, later known as Correlation Spectroscopy (COSY), in which the response of the nuclear spins to two radio frequency pulses is treated by a double Fourier transformation with respect to the delay between the pulses, and the delay after the second pulse. This technique gives detailed information about the molecular links between atoms, inaccessible with previous techniques. [5]
The first experimental demonstration of this technique was carried out by Richard R. Ernst (Nobel prize 1991).[6]
Later, Jeener introduced a variant of 2DNMR, today known as Nuclear Overhauser Effect Spectroscopy (NOESY), that gives detailed information about the spin-lattice relaxation matrix[clarification needed], and about the spatial relation between atoms in complex molecules.[7]
2DNMR and its multi-dimensional extensions[clarification needed] reveal so much more information about the chemical and physical environment of the spins that they have since been used in almost all fields of NMR. [citation needed] Among other applications, they enable detailed reconstruction of the 3-dimensional structure of complex biological macro molecules.
Recognition edit
Jeener is recipient of several distinctions, including the Prix Quinquennal of the Fonds National de la Recherche Scientifique (Prix Dr. A. De Leeuw-Damry-Bourlart), the Prix Ampère, the ISMAR Prize,[8] the Russell Varian Prize,[9] the Otto Stern Prize.[10] He was Doctor Honoris Causa of ETH-Zürich. The Jean Jeener NMR Centre, inaugurated in 2010 at the Vrije Universiteit Brussel, is named after him.[11]
