Different decoupling sequences are tested - using various shaped radio-frequency (RF) pulses - to achieve the longest possible lifetimes of singlet-state populations over the widest possible bandwidths, that is, ranges of offsets and relative chemical shif ...
H-1, P-31, and Li-7 pulsed-gradient spin-echo (PGSE) diffusion and variable-temperature NMR results for THF solutions of the lithium and potassium salts derived from diphenylphosphino(o-cyanophenyl)aniline are reported and compared to the solid-state resul ...
Since many biological processes occur on the μs to ms time scale, internal dynamics on that time scale may well be related to biological functionality. The characterization of internal dynamics is thus an important issue to improve our understanding of the ...
NMR-microprobes based on solenoids and Helmholtz coils have been microfabricated and NMR-spectra of mammalian cells have successfully been taken. The microfabrication technology developed for these probes consists of three electroplated copper levels for l ...
We show how direct spectral optimisation can be used to provide significantly improved resolution for proton NMR spectroscopy in the solid state. We describe the design of new continuous phase modulated schemes for proton-proton homonuclear dipolar decoupl ...
Nuclear magnetic resonance (NMR) signals with short T1 and T2, such as the 13C signal of glycogen, are difficult to localize in three dimensions without major signal loss. A pulse sequence that accomplishes the spatial localization of 1H-decoupled 13C NMR ...
Measuring the nuclear magnetic resonance spectra of low-gamma heteronuclei such as N-15 constitutes an important analytical tool for the characterization of molecular structure and dynamics. The reduced resonance frequencies and magnetic moments of these h ...
A new two-dimensional solid-state NMR experiment, which correlates slow and fast chemical shift anisotropy sideband patterns is proposed. The experiment, dubbed ROSES, is performed under fast magic-angle spinning and leads to an isotropic spectrum in the d ...
Radical C-glycosidation of racemic 5-exo-benzeneselenyl-6-endo-chloro-3-methylidene-7-oxabicyclo[2.2.1]hept an-2-one ((+/-)-2) with alpha -acetobromofucose (3) provided a mixture of alpha -C-fucosides that were reduced with NaBH4 to give two diastereomeric ...
The detn. of the soln. structure of small non-natural oligopeptides and oligonucleotides by NMR, which is one of the main research topics of our group, is illustrated on the example of an 8-mer p-DNA duplex. P-DNA, the 3'-desoxy analog of p-RNA, forms an h ...
