Using NMR parameters, we have previously reported1 the equilibria that exist between the conformers in trans-4-CF,H3\_.-6-methyl-l,3-dioxanes, (I) + (II). Only free energy differences at 300Β°K were obtained. Corresponding derivatives with 2-methyl groups also may be equilibrated under acid conditio
## Abstract The acidity constants of twofold protonated guanosine 5β²βdiphosphate, H~2~(GDP)^β^, and the stability constants of the [Cu(H;GDP)] and [Cu(GDP)]^β^ complexes were determined in H~2~O as well as in 30 or 50% (__v__/__v__) 1,4βdioxane/H~2~O by potentiometric pH titrations (25Β°; __I__=0.1M
