In this contribution we extend the theory of symmetry-based pulse sequences of types CNnν and RNnν in magic-angle-spinning nuclear resonance spectroscopy [Levitt, Encyclopedia of NMR. Vol 9, 165 (2002)] to the case of rotating the sample simultaneously around two different angles with respect to the external magnetic field (double-rotation). We consider the case of spin-1/2 nuclei in general and the case of half-integer quadrupolar nuclei that are subjected to weak radiofrequency pulses operating selectively on the central-transition polarizations. The transformation properties of the homonuclear dipolar interactions and J-couplings under central-transition-selective spin-rotations are presented. We show that the pulse sequence R221R22-1 originally developed for homonuclear dipolar recoupling of half-integer quadrupolar nuclei under magic-angle-spinning conditions [Edén, Chem. Phys. Lett. 431, 397 (2006)] may be used for the same purpose in the case of double-rotation, if the radiofrequency pulses are synchronized with the outer rotation of the sample. We apply this sequence, sandwiched by central-transition selective 90° pulses, to excite double-quantum coherences in homonuclear spin-systems consisting of 23Na and 27Al nuclei.
