Broadband excitation and indirect detection of nitrogen-14 in rotating solids using Delays Alternating with Nutation (DANTE)

► DANTE pulses allow broad band and efficient excitation of 14N spectra. ► Overtone DANTE sequences with 2, 4, and 8 pulses per rotor period are efficient because they require shorter excitation times. ► These excitation schemes can be used for 1D 14N spectra as well as for indirect detection via D-HMQC.
