Abstract
Despite the advantages of compensation for resonance offset and B-1 in homogeneity, adiabatic pulses are not yet in general use in high-resol ution NMR, often because of the conception that these pulses require l onger time or increased power to perform. We show that adiabatic pulse s with tangential frequency sweeps and other frequency-modulation func tions can be optimized to accomplish C-13 and H-1 broadband inversion using pulse lengths of 192 and 64 mu s, respectively, at B-1 strengths available with modern high-resolution probes.
