Quantitative measurement of the relative number of rare spins of individual lines in solid state cross polarization NMR has been hampered by the spin-latlice relaxation in the rotating frame and the finite and different cross polarization transfer rates. In this article a simple method which combine

Order parameters describing conformational exchange processes on the nanosecond to microsecond timescale can be obtained from powder patterns in solid-state NMR (SSNMR) experiments. Extensions of these experiments to magic-angle spinning (MAS) based high-resolution experiments have been demonstrated
## Abstract Powder patterns and sideband patterns have different strengths when it comes to using them to determine chemical shift parameters. Here, we show that chemical shift parameters can be determined with high accuracy by analysing the correlation pattern from a 2D experiment which correlates
