ERNST. RICHARD R. (I933-). A native of Switzerland who won the Nobel prize in chemistry in 1991 for important methodological developments in NMR spectroscopy. He invented Fourier-transform NMR lET-NMR). which multiplied sensitivity It) to 100 times compared to dispersive instruments. He also devised two-dimensional NMR techniques, increasing resolution and enabling structure determinations of biologically important macromolecules. Ernst received his Pli.D from the Federal Technical Institute (ETH) in Zurich. Switzerland... 

The simulated multiplets on p. 9 were produced for us by Jeremy Titman. All the other multiplets and spectra (even the traces in problem 3.9) are authentic. Samples or spectra were donated by Stuart Amor, John Anderson, Mary Baum, Beat Ernst, Richard Ernst, Malcolm Green, Richard Hibbert, Chris Hunter, John Kennedy, Tony Kirby, Antonin Lycka, Gavin Mclnnes, Stephen Matlin, R. Mynott, Clive Pearce, Bill Smith, Tammo Winkler, Victor Wray and tierman Ziffer.

Multidimensional NMR was pioneered by Richard Ernst (Nobel Prize for Chemistry, 1991) and its application to structure determination of biological macromolecules, already heroically undertaken with all the limitations of one-dimensional NMR, was further developed and refined by Klaus Wtithrich (Nobel Prize for Chemistry, 2002). 

Perhaps the first modern analytical studies were those reported in the 1950s on the relationship between smoking and lung cancer. Richard Doll (he appears again ) and Bradford Hill, of England, were the authors of cohort studies of smokers, and Ernst Wynder and Evarts Graham, of the United States, undertook and reported case-control studies of lung cancer cases. The Doll-Hill studies are, in their...

The present suitability and versatility of NMR to study macromolecules has been made available, among others, by the pioneering work of Nobel laureates Richard R. Ernst and Kurt Wiithrich (Nobel Prize in Chemistry, 1991 and 2002). The established protocol of structure determination by NMR consists of the... 

Although I had to abandon the initial arrangement with Professor Eugene G. Rochow for a postdoctoral position, I was still keen to spend a year abroad and, if possible, at a university in the United States. Ernst Otto Fischer strongly supported my intention and recommended, inter alia, Caltech at Pasadena as a top place. One of his former students, Klaus Plesske, was already there and worked as a postdoc with Professor John H. Richards. 

The possibility that a cationic species of the general composition [M2(C5H5)3] + could exist, was first mentioned in a paper published in 1964 [2]. Ernst Schumacher and Richard Taubenest, at that time at the University of Zurich, reported that the ions [Fe2(C5H5)3] + and [Ni2(C5H5)3]+ can be generated from ferrocene and nickelocene in a mass spectrometer under appropriate conditions. The authors concluded that the precursor molecules, after being transformed to the... 

To partially address the problem of resonance offset artifacts, we can first separate the nuclear spin phase evolution induced by the gradient from the evolution induced by all other sources of resonance offset. Nobel Prize winner Richard Ernst introduced a form of imaging that uses pulsed gradients, in analogy...
