Despite the importance of reproducible pulse amplitudes and phases in modem pulse Fourier transform NMR methods, little attention has been paid to the experimental assessment of spectrometer pulse stability. Three methods for determining the phase and amplitude reproducibility of pulses and of the signals they elicit are discussed. The first is based on the measurement of the peak amplitudes of dispersion-mode spectra, the second and most versatile on the method of "tailored detection," and the third on the measurement of the signals produced by closely spaced pairs of pulses. © 1988.
