摘要：

A pulse sequence is presented which allows one to perform an inversion-recovery experiment for T1 determination on quadrupolar nuclei in the presence of acoustic ringing. The sequence is based on a modification of the reference baseline subtraction-90-degrees pulse sequence. Some examples of O-17 and N-14 and relaxation are presented, including spectra with overlapping peaks from which T1 values cannot be simply extracted from line widths.
