The magnetic circular dichroism of 1hyphen;azabicyclolsqb;2,2,2rsqb;octane (ABCO) in then0rarr;3pregion

摘要

An MCD and absorption spectra measured in the energy region of the second excited state of 1hyphen;azabicyclolsqb;2,2,2rsqb;octane (ABCO) reveal large positiveAterms. Simple calculations of the magnetic moment of a1Eexcited state yield also a positive sign for theAterms. A small negativeBterm is observed 355 cmminus;1below the origin of the1Estate. Based onBterm calculations we assign it as the1A1rarr;1A1transition (n0rarr;3pz). The results are compared with a recent MPI study in the same energy range.
