High energy electron beams induce a myriad of changes to molecular crystals. Their impact on crystallinity by way of radiolytic damage is well characterized and has been described as a resolution-dependent decrease in the intensity of Bragg reflections . However, some studies have also noted non-monotonic fluctuations in Bragg reflections during electron beam irradiation . These have been attributed to many potential physical processes, but their true nature remains poorly defined. We chart the degree of non-monotonic fluctuation in diffraction from molecular nanocrystals, and find that Bragg reflections exhibit beam-induced, correlated, and dose-dependent non-monotonic changes in intensity. We propose that these are best explained by crystal lattice reorientation that matches the movement of bend contours across crystals. These observations support a model in which electron beam irradiation directly induces bending or tilting of a crystal lattice.
