3rd Alpine Conference on Solid-State NMR, Chamonix-Mont Blanc, France (Sep. 2003), poster.

We will present new types of symmetry based RNnν [1] pulse sequences for dipolar recoupling in magic-angle-spinning NMR. These schemes have the common feature of being built on pulse elements incorporating windows, which provide high dipolar scaling factors. Demonstrations will include heteronuclear recoupling, enhanced excitation of double- and triple-quantum coherences, and 13C 3Q-1Q correlation spectroscopy.
