摘要: The effect of modulation amplitude on magnetic resonance linewidths δH (between slope extrema) and derivative signal intensity is examined. Experimental results are compared with theory for Lorentzian Gaussian lines. Modulation amplitudes, hm, 0.15δH [or 2hm (peak to peak) = 0.30δH] produce about 2% error in signals less than 1% signals. Effects linewidth presented graphic tabular form.
