 Title    Magnetic Circular Dichroism (MCD) of Four-membered Rings with four jr-Electrons  
 Abstract    On the basis of the perimeter model for 4/V-electron [rc]annulenes, algebraic expressions for the B values of perturbed four-membered rings (n = 4) with four ;r electrons (N = 1) have been derived. The results are used to interpret the MCD spectrum of l,3-di-fm-butyl-2,4-diethyI-1,3,2,4-diazadiboreti-dine.

 Title    Magnetischer Circular Dichroismus (MCD) von cyclischen rc-Elektronensystemen mit 4N±1 Elektronen  
 Abstract    The theory of the magnetic circular dichroism (MCD) of cyclic re-electron systems with 4 N ± 1 electrons, such as the radical anion of [16] annulene, has been investigated in the perimeter model approximation. General solutions and formulas for the calculation of the Faraday parameters A, B, and C are derived analytically. The calculated and measured spectra of the 17 re-electron [16] annulene radical are in good agreement.
