Figure 14
TTF⋯CA – co-existence of the N and I phases in the transition region. The cell dimensions in the upper panel (an embellished view of the lower panel in Fig. 12[link]) show the existence of the two phases. Although there appears to be a small increase in the 020 spacing of the ionic phase at temperatures above the transition temperature, this seems unlikely to be significant because there is much less of the ionic phase and hence the cell dimension measurements are likely to be less precise. The integrated intensity measurements in the lower panel show their relative amounts. The measurements were made at increasing temperatures – the ionic phase diminishes and the neutral phase grows. This is Fig. 4 of Buron-Le Cointe et al. (2003BB14).
