Nuclear Spin-System Dynamics Caused by NMR Saturation for Arbitrary Spin Temperature

1H NMR study of the phase transitions of trissarcosine calcium chloride single crystals at low temperature

“…This technique was known to be efficient and very useful when T 1 was long and a NMR signal was weak [22,23]. The experimental results measured by the progressive saturation recovery technique have been reported for several materials [24][25][26]. In our TSCC case, however, we find from the full recovery pulse sequence that the relaxation profile is not a single exponential type.…”
