摘要：

The Mobius aromatic character of the 8 pi electron transition structure for the conrotatory electrocyclic ring closure of (Z,Z)-octa-1,3,5,7-tetraene is demonstrated by downfield and upfield H-1 chemical shifts as well as the enhanced magnetic susceptibility computed by the IGLO method. H1,8 (outer) are deshielded and H1,8 (inner) are shielded in the transition structure.
