Abstract

The optical spectra of the picrate ion in a micellar solution indicate that slightly below the CMC of CTAB surfactant the anion is relatively free and exists as an ion pair above the CMC. The hydrophobic aggregate of TMAC invariably gives free ion. The polymer micelle of quaternized poly(4-vinylpyridine) results in a tight ion pair.
