Vapor-phase charge-transfer complexes. 12. Dimethyl ether – iodine

Both a modified Benesi–Hildebrand method and the constant activity method were used to study the spectral and thermodynamic properties of the dimethyl ether – iodine complex in the vapor phase and in n-heptane solution. Comparison is made of these results with those for the diethyl ether – iodine complex. The solvent effects on ether – iodine, a relatively weak complex, are compared with those on stronger complexes.
