Summary
Proton- and deuteron magnetic relaxation rates and self-diffusion coefficients have been measured in the system methanol/ cyclohexane at 60°C. The proton relaxation rates were separated into the intra- and intermolecular contributions. By means of the association parameter A strong self-association of methanol with respect to the OH— as well as the CH3-group were revealed. The results indicate that a proper counterpart to the macroscopic characteristics of this system (as e.g. positive deviations from Raoult's law and partial immiscibility) exists on a molecular scale.
