Abstract
The Raman spectra of aqueous solutions of CH3(OCH2CH2)(3)OCH3 were measured for mole fractions 0.002-0.06 at five temperatures between 5 and 45 degree sC. The population of the gauche conformation around the C-C bond shows its maximum at about 0.01 mole fraction. The appearance of the maximum is less prominent at higher temperatures. The observed conformational behavior is consistent with the results of molecular dynamics simulations.
