- W1551236623 abstract "ΔH 1 2 and ΔS 1 2 values for the 1:2 complexes of camphor enantiomers with a-cyclodextrin by NMR titrations, carried out from 25 to 48°C, yielded -16.0′0.2 kcal/mol and 28.3′0.3 e.u. for la@2 and-9.8′0.2 kcal/mol and 9.1′0.2 e.u. for 1b@2. A comparison of the values obtained by other groups, using isothermal titration calorimetry and reversed-phase liquid chromatography, showed considerable differences except the ΔH 1 2 and ΔS 1 2 for 1a@2, obtained by NMR and ITC methods. The reason of the differences, involving RPLC, are not discussed in view of internal inconsistencies ofthis method. On the other hand, the disagreement between the ITC and NMR results seems to be due to the difference in solvents (H 2 O and D 2 O, respectively) used in both methods, which causes deuteration of all 36 OH groups of the host cyclodextrins. Interestingly, the deuteration causes a lowering of the absolute values of ΔH 1 2 and ΔS 1 2 for lb@2, while the corresponding values of the complex with the second enantiomer are either unchanged or undergo only small changes upon the complexation." @default.
