## 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
A fundamental problem in Fourier transform NMR spectroscopy is the calculation of observed resonance amplitudes for a repetitively pulsed sample, as first analyzed by Ernst and Anderson in 1966. Applications include determination of spin-lattice relaxation times (T 1 's) by progressive saturation an
