An early explanation given by Hufner [lo] had to be abandoned in the light of new NMR experiments [12]. UV Extrapolations [Y] suggest AH' = -6.5 kcal.mol-l and ASo = -22 eu for the process Ic --t lc'. Similarly, Roche e f ul. [Ill determined AH"= -6.9 kcal mol-' and AS" = -30 eu for the equilibrium
