Magnetic Circular Dichroism of Molecules in Dense Media: Relation Between Magnetic Circular Dichroism and Hammett's Constants*

摘要

The linear relation between the magnetic circular dichroism (benzene 1A1g → 1B2u transition) of monosubstituted and 1,4-disubstituted benzenes and the substituent constants σ and σR are compared. In all cases, better linear correlations were found between the magnetic circular dichroism and σR. Three series of 1,4-disubstituted benzenes, XC6H4I, XC6H4NO2, and XC6H4CO2H, have been chosen for the magnetic circular dichroism measurements.
