Restructurring dynamics at different initial-equilibrium temperatures and for different orientations. (A) Time-dependent integrated intensities for a set of Bragg (120) spots as a function of initial equilibrium temperature (Te) of the system. The striking retardation of ordering upon increasing Te is evident in the rates that decrease by more than an order of magnitude (see text). Gray bands represent ≥400-ms components (see Fig. S2). (B) Time-dependent intensity change for (120) and (112) Bragg peaks for two different tilt angles θ = 0° and 25°, respectively, at Te = 25 °C (Upper). At θ = 25°, the diffraction of the (112) planes contains molecular information along the c-axis, that is not possible at θ = 0°. The separation change with time observed for θ = 0° is also displayed (Lower).
