Abstract
The disagreement between the absolute configuration of (–)-1,5-diamino-9,10-ethenoanthracene determined by the Bijvoet X-ray method and by the exciton analysis of the c.d. spectrum derives from the use in that analysis of the origin-dependent dipolelength method for the calculation of the transition moments, whereas the employment of the origin-dependent dipole-velocity procedure affords a concordant configurational assignment.Keywords
