Abstract

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