Figure 12
Naphthazarin C: the variation of the integrated intensity as a function of temperature of the 070 reflection, which distinguishes between the disordered phase [stable above 110 K; space group P21/c, (070) absent] and the ordered phase [Pc, (070) allowed]... Neutron diffraction measurements (λ = 0.895 Å) were made for 15 min periods on the D9 reactor at ILL Grenoble. There was no indication of hysteresis. Comparison of Figs. 11[link] and 12[link] shows the different behavior of distinguishing reflections in first- and second-order transitions. Reproduced with permission from Herbstein et al.
