Hardcover Abstract: The data compiled refer to susceptibility measurements (susceptibility, Curie-constants, magnetic moments, transition temperatures) and ESR-measurements (g-factors and other parameters of the applied spin Hamiltonian). In volume II/2 the literature from 1899 up to 1964 has been considered. Volume II/8 supplements volume II/2, taking into account the data on magnetic susceptibilities and ESR parameters published in the p eriod 1964 to 1968. The following subvolumes II/10,II/11, II/12 supplement data up to 1974.

Hardcover Abstract: Volume II/25 is a supplemented and revised edition of the preceding volumes II/7, II/15, II/21 and II/23 containing up to date information on inorganic and organic polyatomic molecules. All experimental methods for the determination of quantitative structural data of free molecules have been considered: microwave, infrared, Raman, electronic and photoelectron spectroscopy as well as electron diffraction. The data obtained by these methods have been critically evaluated and compiled. They are presented separately for each molecule, together with a schematic figure of the structure and the original literature.
