Abstract A pulse sequence is proposed for the effective elimination of baseline distortions due to acoustic ringing in pulsed Fourier transform NMR spectroscopy. The method utilizes only 90° pulses with the same phase, and is based on the amplitude and phase characteristics of the distortions. The efficiency of the technique for recording resonances of low‐frequency nuclei having extremely fast relaxation rates, the achievable sensitivity and the off‐resonance effects are discussed.
