## Abstract Spinβlattice relaxation mechanisms of nuclear spins in solids in the presence of low concentrations of paramagnetic centers are discussed. Apart from the electron spinβlattice relaxation mechanism, threeβspin processes involving two electron spins and a nuclear spin may also play a role

## Abstract A pulse sequence is presented which allows measurement of short __T__~1~ values (< 1 s) in solids, avoiding probe damage by the use of saturating sequences of 90Β° pulses. The use of the sequence is illustrated for a crossβlinked polymeric system which contains composite peaks having bot
The goal of this work is to provide regional T(1) and T(2) values at a field strength of 7 T for the normal mouse brain at 6 weeks and 1 year old. A novel segmented snapshot FLASH sequence was used to measure T(1) in the hippocampus, corpus callosum, and the retrosplenial granular (RSG) cortex; T(2)
