Question: Aromatic hydrocarbons and 12 form complexes from which charge transfer electronic transitions are observed the hydrocarbon acts as an electron donor and 12 as an

Aromatic hydrocarbons and 12 form complexes from which charge transfer electronic transitions are observed the hydrocarbon acts as an electron donor and 12 as an electron acceptor the energies hvmax of the charge-transfer transitions for a number of hydrocarbon-I, complexes are given below: Hydrocarbon benzene biphenyl naphthalene phenanthrene pyrene anthracene hvmax/eV 4.184 3.654 3.452 3.288 2.989 2.890 Investigate the hypothesis that there is a correlation between the energy of the HOMO of the hydrocarbon (from which the electron comes in the charge-transfer transition) and hvmax' Use one of the molecular electronic structure methods discussed in Chapter 11 to determine the energy of the HOMO of each hydrocarbon in the data set. 1
