A novel method to realize rapid repetition of 1 H NMR experiments at ultra-fast MAS
frequencies is demonstrated. The ultra-fast MAS at 110 kHz slows the 1 H–1 H spin
diffusion, leading to variations of 1 HT 1 relaxation times from atom to atom within a
molecule. The different relaxation behavior is averaged by applying 1 H–1 H recoupling
during relaxation delay even at ultra-fast MAS, reducing the optimal relaxation delay to
maximize the signal to noise ratio. The way to determine optimal relaxation delay for …
