摘要
The magnetic circular dichroism (MCD) spectra of decacyclene (I) and hexabenzocoronene (II) have been measured. The absorption spectra of I and II located in the lowest wavenumber region (22-30×103 cm -1) were assigned by using the MCD spectra and the results of the SCF screened potential π-MO CI calculations. The 1E′ and 1Elu excited states of I and II are located at 26.5 and 26.1×103 cm respectively. The calculated Faraday A/D values for these excited states agreed well with the experimental values both in signs and in magnitudes. The calculated Faraday B values for these excited states tended to be larger than the experimental values. © 1979 American Institute of Physics.
