Deuterium N.M.R. of then-octyl-β-D-glucopyranoside-solvent liquid-crystalline systems

Abstract

Deuterium quadrupolar splittings were measured as a function of concentration and temperature for deuteriated water, benzene-d ₆, toluene-d ₈ and acetonitrile-d ₃, dissolved in n-octyl-β-D-glucopyranoside (OG). The splittings and temperature dependence are larger for the apolar solvents. Water forms rather rigid structures with OG as indicated by its large linewidths. OG can accommodate both water and benzene (or toluene) together and the results for such systems are also reported. Some additional results for the hydroxyl deuteriated OG and for a system containing a lower homologue of OG are reported.
