Abstract: | The study of the ethylene thiourea-iodine charge-transfer complex in various solvents like CH2Cl2, CHCl3, CHCl3:CCl4 solvent mixtures and 1,2-dichloroethane reveals a good correlation for the equilibrium constants and other thermodynamic quantities with the extinction coefficients in various chlorinated methane solvents. |
