Abstract
Size variation of samples subjected to NMR examinations entails the need for calibration of the radiofrequency excitation which gives rise to the resonance phenomenon measured during experiments. Determination of the most suitable value of the radio-frequency excitation amplitude is carried out by scanning the range of potential amplitudes, starting from one end of the range. During the scanning operation, the variation in excitation amplitude varies in a geometrical progression with the order number of the experimentation. It is shown that, by adopting this procedure, determination of the calibrated amplitude is achieved more rapidly while maintaining constant accuracy of determination.
