Figure 6
Principal and volume thermal expansion coefficients of MS9 as a function of temperature. Solid lines are derived from smoothed values calculated using the Einstein-model fit parameters reported in Table 3. Symbols are `point-by-point' derivatives of the raw cell parameter values calculated across a moving window 15 K wide. The dashed red line in (d) depicts the volume thermal expansion of MS11 for comparison with that of MS9: the dotted blue line represents the unconstrained double-Debye model fit to the data (see text in the supporting information) |
