Pseudorandom selective excitation in NMR

►Variant of DANTE using random pulse delays and phase modulated θ-pulses, pseudorandom DANTE (p-DANTE), is presented. ► An average Hamiltonian theory (AHT) description for DANTE and p-DANTE was developed, valid in nonlinear regime Θ > π/3. ► AHT description breaks down just above and below the resonance conditions of the DANTE and p-DANTE pulses. ► Averaging over different p-DANTE sequences improves the selectivity of exciting a single resonance.
