(a) Mean-square displacement of protons as extracted from the loss of intensity using the DAVE data analysis software (26). A line is drawn to indicate a linear regime up to ≈200–250 K. Data are drawn up to the melting transition due to deviations from linearity of ln I vs. Q2 above 340 K. (b) Loss of intensity as a function of Q2 for three separate temperature regimes. Errors are within the symbol size.
