Dipolar recovery

A number of recoupling techniques are utilized for specific purposes, but they all rely on synchronizing measurements, and, in most instances, pulse sequences, with the rotation period. For homonuclear recoupling (e.g., 13C-13C or 31P-31P), rotational resonance (R2) is based on magnetization exchange when the spinning rate wr is adjusted so that a multiple of it equals the chemical shift difference between the two dipolar coupled nuclei, and DRAMA (dipolar recovery at the... [Pg.197]

The first experiment to reintroduce homonuclear dipolar coupling under MAS conditions by applying a multiple-pulse sequence was DRAMA (dipolar recovery at the magic angle). The basic sequence of DRAMA consists of two 7t/2 pulses in each rotation period to spoil the averaging of the dipolar coupling interaction by MAS. In the complete DRAMA sequence (Fig. 25)... [Pg.233]
