Expressions for the random‐distribution and cluster‐formation models for light‐induced changes in crystals studied by time‐resolved diffraction are presented. The two models can be distinguished on the basis of differences in the predicted intensities. The light‐induced increase in the atomic displacement parameters is analyzed with both simulated and experimental data sets.
