Magnetic Circular Dichroism of Molecules in Dense Media: Relation Between Magnetic Circular Dichroism and Hammett's Constants.
The linear relation between the magnetic circular dichroism (benzene (1)A(1g) --> (1)B(2u) transition) of monosubstituted and 1,4-disubstituted benzenes and the substituent constants sigma and sigma(R) are compared. In all cases, better linear correlations were found between the magnetic circular dichroism and sigma(R). Three series of 1,4-disubstituted benzenes, XC(6)H(4)I, XC(6)H(4)NO(2), and XC(6)H(4)CO(2)H, have been chosen for the magnetic circular dichroism measurements.
