The volume II/27A has been divided into three subvolumes according to the classes of compounds: Subvolume A: Diamagnetic susceptibility and magnetic anisotropy of inorganic and organometallic compounds; Subvolume B: Diamagnetic susceptibility of organic compounds (Part 1); Subvolume C: Diamagnetic susceptibility and magnetic anisotropy of organic compounds (Part 2). The data presented in this volume are based on the literature survey of the chemical abstracts up to 2005.
