摘要：

A pulse sequence is presented which allows measurement of short T1 values (< 1 s) in solids, avoiding probe damage by the use of saturating sequences of 90° pulses. The use of the sequence is illustrated for a cross‐linked polymeric system which contains composite peaks having both short‐T1 and long‐T1 components. Copyright © 1990 John Wiley & Sons, Ltd.
