Magnetic interactions of nuclei with eachother and with the electric field due to electrons lead to broadening of the linewidths of NMR spectra of static powder samples. Most interactions can be averaged by a rapid rotation of the sample around an axis that is tilted through the 'magic angle', 54°, with respect to the static field. Very fast spinning, typically beyond 30 kHz, leads to very effective averaging and, therefore, to narrow and more intense lines. The technology of Magic-Angle Spinning (MAS) has evolved over the last decades, to the point where today the most reliable rotors can spin with speeds up to 70 kHz.We aim to acquire a fast-spinning detection probe in order to ensure that our research on improvement of heteronuclear decoupling methods, recoupling methods, and indirect detection of nitrogen-14 achieves its full potential.
