Abstract
The i.r. spectra of binary mixtures of water (HDO and H2O) and four non-electrolyte cosolvants: acetonitrile, dioxane, dimethylsulfoxide, and hexamethylphosphorotriamide have been recorded from 3700 to 3100 cm−1, the mole fractions of water varying from 0 to 1. The investigation of the OH stretching bands of water suggests the presence of various types of hydrogen bonded complexes and confirms the existence of well-defined I–II complexes (one molecule of water bonded to two molecules of cosolvent) when Xwater < 0.1. In the range 0.8 < Xwater < 1 the organic cosolvent has negligible effect on the spectrum of water.Keywords
