Abstract

The IR spectra of solutions of HF in methanol have been measured as the molar ratio of the components is varied from 1:12 to 7:1. The features of the absorption of HF-CH<sub>3</sub>OH binary mixtures of various concentrations are analyzed, and the spectral attributes of the molecular heterocomplexes present in them are explained. It is established by analyzing the concentration dependence of the optical density of the test solutions, normalized to the total number of moles per liter, that associates of molecules are formed in them with stoichiometric HF:CH<sub>3</sub>OH ratios equal to 2:1 and about 6:1. These results are compared with analogous data obtained from the concentration dependence of the excess density of solutions of HF in methanol.
