A comparison of SCA-simulated precession intensity pendellösung data for [001]-TIPS pentacene and rubrene with Bloch wave results. The electron-beam precession angle is 2°. smax values of 5.8 × 10−3 Å−1 and 3.9 × 10−3 Å−1 were used for SCA simulations of TIPS pentacene and rubrene, respectively. The SCA slice thickness Δz was either 0.5 Å or 1.0 Å. For TIPS pentacene, precession intensities are plotted for (a) the 000, (b) the 100 and (c) the 500 reflections, while for rubrene the intensities correspond to (d) the 000, (e) the 010 and (f) the 050 beams. The SCA pendellösung data for the two Δz values directly overlap in panels (a) and (d). The total electron intensity is normalized to unity.
