Complex permittivity spectra of methanol-tetrachloromethane mixtures at 25-degrees-C are presented, covering the frequency range 0.95 less-than-or-equal-to v/GHz less-than-or-equal-to 89. The mole fraction x2 Of CCl4 is varied in the range of 0 less-than-or-equal-to x2 less-than-or-equal-to 0.59. A dielectric relaxation model for methanol with superposition of 3 Debye equations must be used to fit the data for all studied mixtures. Concentration dependence of the relaxation times and dispersion amplitudes reveal hydrogen bonding between the methanol molecules as the dominating type of interaction. A model is proposed for the calculation of the fraction of alcohol monomer and chain-end molecules and the results from high frequency permittivity measurements are compared with information from other methods. A relaxation mechanism is proposed involving three modes for methanol.
