It was found that the changes in the values of the mean least intermolecular distances with increasing concentration of the solution of 2-methyl-2-propanol in carbon tetrachloride were not linear. Within the range of low concentrations,i.e.from 0.07–0.08 molar fraction, a local minimum of the values of the mean least intermolecular distance was found to cccur. This value remains stable within the range from 0.1 to 0.6 molar fraction, and then decreases to the minimum value for pure 2-methyl-2-propanol. The results obtained in this work confirm the specific structural properties of the solution in the lower concentration range.
