Design and application of robust rf pulses for toroid cavity NMR spectroscopy

► Robust point-to-point rotation pulses that tolerate a factor of 6 RF spatial inhomogeneity in toroid probes. ► Robust universal rotation pulses that tolerate a factor of 6 RF spatial inhomogeneity in toroid probes. ► Practical implementation of 2D spectroscopy in a toroid probe.
