In solids spinning at the magic angle, the indirect detection of single-quantum (SQ) and double-quantum (DQ) N-14 spectra (l = 1) via spy nuclei S = 1/2 such as protons can be achieved in the manner of heteronuclear single- or multiple-quantum correlation ...
Purpose: To improve the traditional Nyquist ghost correction approach in echo planar imaging (EPI) at high fields, via schemes based on the reversal of the EPI readout gradient polarity for every other volume throughout a functional magnetic resonance imag ...
Recent years have witnessed increased efforts toward the accelerated acquisition of multidimensional nuclear magnetic resonance (nD NMR) spectra. Among the methods proposed to speed up these NMR experiments is "projection reconstruction," a scheme based on ...
Despite obvious improvements in spectral resolution at high magnetic field, the detection of C-13 labeling by H-1-[C-13] NMR spectroscopy remains hampered by spectral overlap, such as in the spectral region of H-1 resonances bound to C3 of glutamate (Glu) ...
A double-zero quantum (DZQ)-refocused INADEQUATE experiment is introduced for J-based NMR correlations under ultra-fast (60 kHz) magic angle spinning (MAS). The experiment records two spectra in the same dataset, a double quantumsingle quantum (DQ-SQ) and ...
