  Lee-Goldburg cross polarization is used in many NMR experiments to determine
internuclear distances. Distances calculated from frequency peaks in the
dipolar coupled dimension are subject to scale factors. Experimentally
determined scale factors can differ significantly from the theoreticalyy useful
value described in the literature. In this work, simulations using
SPINEVOLUTION explore effects of varying experimental parameters of frequency
offset and cross polarization powers on $^{15}$N-H systems. Experimental data
is used to corroborate the simulation. The scale factor is shown not only to
depend on the offset frequency but also the cross polarization powers of the
observed nucleus. Scale factors greater than one are shown to be possible in
simulated data, though such factors obscure the determination of internuclear
distances.
