Double Rotation

Double rotation (DOR) spins a small inner rotor inside a larger outer rotor. The simultaneous sample rotation about the two axes leads directly to isotropic high-resolution spectra of half-integer quadrupolar nuclei.

A double rotation probe is available to users at the 800MB or 720 MHz NB systems. Its 4 mm inner rotor spins inside the slower 9 mm outer rotor with 6 kHz and 1.5 kHz maximum speeds, respectively.

The following spectrometers are available for this technique:
