Abstract
NMR spectroscopy at ultra-high magnetic fields requires improved radiofrequency (rf) pulses to cover the increased spectral bandwidth. We introduce optimized 90° pulse pairs as Ramsey-type cooperative (Ram-COOP) pulses for biomolecular NMR applications. The Ram-COOP element provides broadband excitation with enhanced sensitivity and reduced artifacts even at magnetic fields >1.0 GHz 1H Larmor frequency (23 T). A pair of 30 ?s Ram-COOP pulses achieves an excitation bandwidth of 100 kHz with a maximum rf field of 20 kHz, more than three-fold improved compared to achievable excitation by rectangular pulses. Ram-COOP pulses exhibit little offset-dependent phase errors and are robust to rf inhomogeneity. The performance of the Ram-COOP element is experimentally confirmed with heteronuclear multidimensional NMR experiments, applied to proteins and nucleic acids. Ram-COOP provides broadband excitation at low rf field strength suitable for application at current magnetic fields and beyond 23 T.

Enhancing the sensitivity of multidimensional NMR experiments by using triply-compensated Ï? pulses Enhancing the sensitivity of multidimensional NMR experiments by using triply-compensated Ï? pulses Abstract In multidimensional solution NMR experiments, Ï? pulses are used extensively for inversion and refocusing operations on 1H, 13C and 15N nuclei. Pulse miscalibration, off-resonance effects, and J-coupling evolution during Ï? pulse execution result in severe signal losses that are exacerbated at high magnetic fields. Here, we report the implementation of a triply-compensated Ï? pulse (G5) optimized for both inversion and refocusing in widely used...	nmrlearner	Journal club	0	11-21-2017 10:10 PM

Simultaneous convection compensation and solvent suppression in biomolecular NMR diffusion experiments Simultaneous convection compensation and solvent suppression in biomolecular NMR diffusion experiments Abstract Thermal convection and high intensity solvent resonances can significantly hamper diffusion estimates in pulsed gradient spin-echo nuclear magnetic resonance diffusion experiments on biomolecule samples. To overcome these two problems, a new double functional NMR diffusion sequence, double echo PGSTE-WATERGATE, is presented. The new sequence provides excellent convection compensation and solvent suppression (with a suppression factor in excess of at least 105 in a single scan)...	nmrlearner	Journal club	0	01-09-2011 12:46 PM
