He was born in Brussels in 1931, son of Raymond Jeener (biologist) and Hélène Massar. He is married to Françoise Henin. Early life{{expand section|date=November 2012}}Jeener grew up in Brussels. CareerJeener 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.[1] Nuclear magnetic resonance spectroscopyJeener is best known for introducing two-dimensional NMR spectroscopy (2DNMR). In a lecture at the AMPERE Summer School in Basko Polje, Yugoslavia, September 1971,[2][3] 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. {{citation needed|date=October 2011}} The first experimental demonstration of this technique was carried out by Richard R. Ernst (Nobel prize 1991).[4] 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{{clarify|date=October 2011}}, and about the spatial relation between atoms in complex molecules.[5] 2DNMR and its multi-dimensional extensions{{clarify|date=October 2011}} 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|date=October 2011}} Among other applications, they enable detailed reconstruction of the 3-dimensional structure of complex biological macro molecules. {{further|Nuclear magnetic resonance spectroscopy of proteins}}RecognitionJeener 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,[6] and the Russell Varian Prize.[7] He is Doctor Honoris Causa of ETH-Zürich. The Jean Jeener NMR Centre, inaugurated in 2010 at the Vrije Universiteit Brussel, is named after him.[8] Selected journal publications
