Figure 8
Double-well potential-energy function of C(5) in the 2-methyl-1,3-cyclohexanedione ring below [T_c], with indicated centres of two energy levels, one close to the bottom and the other close to the top of the barrier. The energy of activation ΔEa and the difference between the minima ΔEp were obtained from NMR studies by Waôsicki et al. (1995BB58). Ea changes to 26.1 kJ mol-1 above 244 K.
