Chemical shift correlation at high MAS frequencies employing low-power symmetry-based mixing schemes

Chemical shift correlation at high MAS frequencies employing low-power symmetry-based mixing schemes

Abstract An approach for conveniently implementing low-power CN n Î½ and RN n Î½ symmetry-based band-selective mixing sequences for generating homo- and heteronuclear chemical shift correlation NMR spectra of low Î³ nuclei in biological solids is demonstrated. Efficient magnetisation transfer characteristics are achieved by selecting appropriate symmetries requiring the application of basic RF elements of relatively long duration and numerically tailoring the RF field modulation profile of the basic element. The efficacy of the approach is experimentally shown by the acquisition of 15Nâ??13C dipolar and 13Câ??13C scalar and dipolar coupling mediated chemical shift correlation spectra at representative MAS frequencies.

31P NMR correlation maps of 18O/16O chemical shift isotopic effects for phosphometabolite labeling studies 31P NMR correlation maps of 18O/16O chemical shift isotopic effects for phosphometabolite labeling studies Abstract Intramolecular correlations among the 18O-labels of metabolic oligophosphates, mapped by J-decoupled 31P NMR 2D chemical shift correlation spectroscopy, impart stringent constraints to the 18O-isotope distributions over the whole oligophosphate moiety. The multiple deduced correlations of isotopic labels enable determination of site-specific fractional isotope enrichments and unravel the isotopologue statistics. This approach ensures accurate determination of 18O-labeling...	nmrlearner	Journal club	0	06-06-2011 12:53 AM
Sensitive 13Câ??13C correlation spectra of amyloid fibrils at very high spinning frequencies and magnetic fields Sensitive 13Câ??13C correlation spectra of amyloid fibrils at very high spinning frequencies and magnetic fields Abstract Sensitive 2D solid-state 13Câ??13C correlation spectra of amyloid Î² fibrils have been recorded at very fast spinning frequencies and very high magnetic fields. It is demonstrated that PARIS-xy recoupling using moderate rf amplitudes can provide structural information by promoting efficient magnetization transfer even under such challenging experimental conditions. Furthermore, it has been shown both experimentally and by numerical simulations that the method is not...	nmrlearner	Journal club	0	04-01-2011 09:23 AM

Broadband 15Nâ??13C dipolar recoupling via symmetry-based RF pulse schemes at high MA Abstract An approach for generating efficient RNnnS, nk symmetry-based dual channel RF pulse schemes for Î³-encoded broadband 15Nâ??13C dipolar recoupling at high magic angle spinning frequencies is presented. The method involves the numerical optimisation of the RF phase-modulation profile of the basic â??Râ?? element so as to obtain heteronuclear double quantum dipolar recoupling sequences with satisfactory magnetisation transfer characteristics. The basic â??Râ?? element was implemented as a sandwich of a small number of short pulses of equal duration with each pulse characterised by...	nmrlearner	Journal club	0	08-14-2010 04:19 AM
