“…Substances of the following classes were used as solutes: oxygen, nitrogen and halogen derivatives of benzene, alkylbenzenes, paraffins and cycloparaffins; and ketones, nitriles and some heterocyclic compounds (Table II). The calculated values of gaseous phase dipole moments of solute molecules 2k were obtained within the limits of the original Onsager model [11], k = 1, its modification [12], k = 2, and our approach [1], k = 3. The results are shown in Table II Interpreting the experimental data and theoretical results, we notice the following.…”
