✦ Synopsis

A method is presented for eliminating ringing effects in pulsed nuclear magnetic resonance (NMR) by using a composite pulse with phase cycling. This method can readily be used in a wide variety of pulse sequences, especially in multiple-pulse sequences, such as in WHH-4 and MREV-8. Experimental results show that the proposed composite puke is quite effective.

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
