(a) Simulated absorption spectrum of a nitroxide at 9.5 GHz where gx = 2.0085, gy = 2.0061, gz = 2.0023; Ax = 6.2 G, Ay = 4.3 G, Az = 36.9 G; and τR = 8 × 10−10 s.

(b) Pseudomodulation of absorption spectrum with amplitudes of 0.25, 0.5, 1.0, and 2.0 G, resulting in progressively greater signal intensity. Note the change in vertical scale.

(c) Integration of the pseudomodulated spectra. Spectra have been normalized to one for comparison. Relative peak heights of the three lines are fairly well preserved. (d) Residual of the integrated pseudomodulated spectrum subtracted from the unmodulated spectrum in (a). Field modulation results in line-broadening under all conditions.
