    • note
    • Preliminary results suggest that the width of the observed glass transition, which is twice as large as the one predicted by the simple two-state model [31], cannot be explained by a simple distribution of τ's; rather there is evidence for a well-defined substructure in the glass transition for 6.6 < cursive chi ≤ 6.95 (Ref. [18]).

    • note
    • Interestingly, the negative contribution to the expansivity of the α axis means that the length of the a axis will increase during relaxation after a quench from high temperatures to room temperature. This is opposite to the result of Jorgensen et al. for cursive chi = 6.4 (see Ref. [9]).

    • See, for example, [31]. The formula in Ref. [31] is, however, only approximate, and the exact result is given by Eq. (2).
