The diamagnetism of 1,8 bisdehydro[14]annulene

Abstract

The principal molecular susceptibilities of bisdehydro [14]annulene, determined from measurement of the diamagnetic anisotropy of a single crystal, are -20, -24 and -358 (• The results are in agreement with a London calculation of the ~r-electron contribution to the molecular anisotropy.
