Figure 1

Selected snapshots during isothermal transformation of ethanol into PC phase. Simultaneous dielectric loss spectroscopy curves (a) and neutron diffraction patterns (b) are presented during isothermal annealing at 105 K. ND patterns for every time are represented as a function of the scattering vector $\mathbf{Q}$. DS spectra are given for every time as a function of the frequency. Every pattern was recorded with an acquisition time of 10 min. Annealing time is indicated in hours.Reuse & Permissions

Figure 2

Selected neutron diffraction pattern (4.8 h) for isothermal transformation of SCL ethanol into PC at 105 K. The red continuous line is a fit of the total diffraction pattern to a linear combination of the measured diffraction patterns at the initial (SCL, green line) and final (PC, blue line) times. In the inset we show the time dependence of the PC fraction.Reuse & Permissions

(a) Fitting of the dielectric relaxation curve for annealing time of 2.5 h during transformation of SCL ethanol into PC at 105 K. Green, black, and blue solid lines stand for the SCL, interface, and PC phases, respectively. (b) Time evolution of the fraction associated with the coexisting phases: ○ the PC calculated by ND, △ the interface, and $\otimes$ the SCL. Normalized total dielectric strength (□) is also shown for comparison. (c) Normalized dielectric strength to its initial value for the SCL and interface relaxations of deuterated ethanol as a function of the PC degree of order. (d) Characteristic relaxation time for the main relaxation assigned to the precursor phase as a function of the PC degree of order.Reuse & Permissions
