Abstract

A relation between the quadrupole coupling constant e²Qq_zz and asymmetry parameter η has been found for a series of meta-substituted iodobenzene derivatives. The relationships e²Qq_zz(η) for electrondonor and electron-acceptor substituents have the same form but different numerical values of parameters. The average time of full electron transfer via tunneling has been evaluated.
