Lee-Goldburg cross polarization is used in many NMR experiments to determineinternuclear distances. Distances calculated from frequency peaks in thedipolar coupled dimension are subject to scale factors. Experimentallydetermined scale factors can differ significantly from the theoreticalyy usefulvalue described in the literature. In this work, simulations usingSPINEVOLUTION explore effects of varying experimental parameters of frequencyoffset and cross polarization powers on $^{15}$N-H systems. Experimental datais used to corroborate the simulation. The scale factor is shown not only todepend on the offset frequency but also the cross polarization powers of theobserved nucleus. Scale factors greater than one are shown to be possible insimulated data, though such factors obscure the determination of internucleardistances.
