A theoretical framework is constructed to treat the effects of salt ions on polyionic structural transitions in the absence of specific ion binding. As an application, the salt concentration-dependent part of the free energy difference governing the B----ZI transition of [d(C-G) . d(C-G)]6 in 1:1 electrolytes is calculated; quantitative agreement with the experimental findings is obtained. The effects of temperature and multivalent cations are also discussed. Preliminary calculations indicate… CONTINUE READING
