## Abstract **Summary:** Polyelectrolyte complexes have been elaborated by mixing in water neutral poly(__Ξ²__βCD), a cationic surfactant (DTAC) and herring sperm DNA fragments. The driving forces for the poly(__Ξ²__βCD)/DTAC/DNA association in aqueous solution are, on the one hand, reversible inclus

Abstract
In low dielectric solvents such as pyridine or isopropylamine, sodium perchlorate interacts strongly with a variety of sugars. The interaction is best described as nonβspecific, with close proximity of the ionic partners maintained, as in a sugarβshared ion pair.

The substitution reaction between aquopentacyanoferrate(I1) and tetraamminepirazynecarboxylatocobalt(II1) to form a binuclear species is studied in various binary aqueous mixtures at different temperatures. Values of activation parameters seem to indicate no change in the mechanism of the reaction i
