By using low temperatures and largely deuterated solvents, the rate of OH proton exchange for aqueous soWions of alcohols is reduced sufficiently to give separate NMR signak from water and alcohol OH protons. The limiting shifts for dilute alcohols in water are down-field of both the water resonance
## Abstract **Summary:** The thermosensitive phaseβseparation of poly(vinyl methyl ether) in water has been investigated by microβRaman spectroscopy in the presence of tetraalkylammonium bromides. The equilibrium distribution of both polymer and salts to the polymerβrich and solventβrich phases was
