## Synopsis The vacuum CD spectra of poly(rGdC).poly(rGdC) and poly(dG-m 5dC).poly(dG-m5dC) have been obtained for the low-salt Zconformations of both polymers. The spectra are very similar to those for the high-salt Zforms. This behavior is consistent with the suggestion that the lowand high-salt
A timeresolved fluorescence study of ethidium bromide (EB) in the presence of poly(dGdC) and of poly(dGdC) modified by chlorodiethylenetriamine platinum(I1) chloride is presented under solvent conditions in which these polymers adopt the Z-conformation (high ionic strength). It is shown that these p
