Abstract
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 and Gaussian lines. Modulation amplitudes, hm, of 0.15δH [or 2hm (peak to peak) = 0.30δH] produce about 2% error in linewidths for Lorentzian signals and less than 1% error for Gaussian signals. Effects of modulation on linewidth and signal amplitude are presented in graphic and tabular form.Keywords
