Figure 2 . Magnitudes and positions of vectors of dipole moments of the two enantiomeric S(-) and R(+) forms of CQ in gas phase by using hybrid B3LYP/6-311++G** method.
The differences observed in the dipole moments could have some effect on their properties, especially in aqueous solution. Therefore, the solvation energies are useful parameters highly related to the presence of acceptor and donors H bonds in solution. Hence, for the two enantiomeric S(-) and R(+) forms of CQ the corrected and uncorrected solvation energies by zero point vibrational energy (ZPVE) by using the B3LYP/6-311++G** method are presented in Table 2 .
