Abstract

A pulse sequence is presented which allows one to perform an inversion–recovery experiment for T~1~ determination on quadrupolar nuclei in the presence of acoustic ringing. The sequence is based on a modification of the reference baseline subtraction −90° pulse sequence. Some examples of ^17^O and ^14^N and relaxation are presented, including spectra with overlapping peaks from which T~1~ values cannot be simply extracted from line widths.
