Update: 30 September, 2023
This application note describes the applications and experimental considerations for FastMAS and UltraFastMAS techniques. FastMAS and UltraFastMAS techniques enable experiments with rotation speeds of 40 to 65 kHz, which reduces linewidths and suppresses spin diffusion caused by proton-proton dipolar interactions. These techniques enable experiments such as direct proton observe or solid-state HETCOR to collect spectra comparable to those that formerly required both spinning and experimentally difficult multiple-pulse homonuclear decoupling sequences. Another advantage of FastMAS and UltraFastMAS techniques is that they suppress spin diffusion between protons, allowing experiments to be conveniently performed on individual protons in single or multiple dimensional experiments.
