Rech. Fond. Matiere Cond., SPSMS-MDN, CEA/Grenoble, 17 rue des Martyrs, 38054 Grenoble Cédex 9, FranceAbstract: The determination of magnetization density distributions using polarized neutron diffraction has played a key role during the last fifteen years in the emerging field of molecular magnetism. In the present article, an introduction to this branch of material science and to the experimental technique is given. The data treatment methods are briefly reviewed and some recent results are presented. A particular attention is given to the members of the nitronyl nitroxide free radicals family, which are widely used in the construction of organic magnetically ordered materials. The main features of the magnetization density in isolated radicals are presented. Spin polarization and spin delocalization effects encountered in this class of compounds are discussed. Then it is shown how the magnetic interactions with neighbouring molecules can propagate through hydrogen bonds or through intermediate atoms and how they modify the main features found in isolated species. In the case of a direct coordination to a transition metal ion, it is shown how drastic can be the modifications on the spin density, depending on the strength of the magnetic couplings.

Part 2 (of 2), October 16, 1994 - October 21, 1994; Publisher: Gordon & Breach Science Publ IncAuthor affiliation:1Osaka City Univ, Osaka, JapanAbstract: Recently, organic high-spin polymers and clusters have been emerging. With the increasing effective molecular spin quantum number S and molecular weight of the polymers, however, cw ESR spectroscopy manifests its inherent disadvantages in discriminating high spins from S = 1/2 and in determining the S's for the complex mixture of various spin assemblages. An electron spin transient nutation method based on pulsed ESR spectroscopy has been for the first time applied to a quasi 1D high-spin polymer as one of the most complex amorphous spin assemblages, identifying that the polymer is comprised of high-spin assemblages with the S's greater than two. It can be concluded that electron spin transient nutation spectroscopy is a facile and useful method for the exclusive identification of S and ESR transitions even for the cases of apparently vanishing fine-structure splittings and for spin systems with residual fine-structure terms in the spin Hamiltonian. Fundamental bases for the transient nutation method are described, emphasizing inherent advantages in thenutation spectroscopy from the methodological viewpoint. The salient features of multiple-quantum nutations have been disclosed in this work.
