Dual-band selective double cross polarization for heteronuclear polarization transfer between dilute spins in solid-state MAS NMR

► Sine modulation was proposed for dual-band selective DCP experiments. ► Dual-band selective DCP experiments used less RF power for better selectivity. ► Dual-band selective DCP experiments were insensitive to the RF variation. ► NCO/NCA spectra of GB1 were obtained simultaneously in a single experiment.
