✦ Synopsis

A full investigation of the possible homonuclear double-quantum recoupling sequences, based on the RN family of sequences with N < or = 20, is given. Several new RN sequences, R16(6)(5), R18(8)(5), and R18(10)(5), were applied at high magic-angle spinning rates and compared with theory. The R18(10)(5) technique can be used to recouple dipolar couplings at spinning rates up to 39 kHz, and the application of the sequence in an INADEQUATE experiment is shown for a spinning rate of 30 kHz.

Heteronuclear dipolar recoupling with rotational-echo doubleresonance (REDOR) is investigated in the rapid magic-angle spinning regime, where radiofrequency irradiation occupies a significant fraction of the rotor period (10 -60%). We demonstrate, in two model 13 C-15 N spin systems, [1-13 C, 15 N]

## Abstract We applied the POST‐C7 DQ‐dipolar recoupling pulse sequence to the measurement of ^1^H–^1^H distances with high precision. The spectral resolution is enhanced by detecting the ^1^H magnetization via ^13^C signals. A least‐squares fitting of the build‐up curve of the transferred magnetiz

It is demonstrated that a high-resolution (1)H NMR spectrum of excised rat liver can be obtained using the technique of magic angle turning (MAT) at a sample spinning rate of 1 Hz. A variant of the phase-corrected MAT (PHORMAT) pulse sequence that includes a water suppression segment was developed f
