## 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 exampl
was evaluated for in vivo brain proton surface coil NMR spectroscopy. The studies were performed on cat brain using surface coils at 4.7 T. The sequence produced brain spectra with adequate water suppression, and a broader excitation profile than sequences which form spin echoes using 133 1 pulses (
