Monomeric and polymeric iron phthalocyanines (FePc) with and without carbon support and subjected to various heat treatments have been studied by Mössbauer spectroscopy. Dispersing FePc on carbon changes the electronic state of the monomer to low spin (S = 0) while the electronic state of the polymer remains unchanged (S = 1). It is suggested that the bonding between polymeric FePc and carbon takes place through the side groups present on the peripheral parts of the polymer and/or through suitable chemical groups present on the carbon surface. The electron-attracting ability of the side-groups deduced from the Mössbauer spectra is discussed. The results will form a basis for a comparison with data from electrochemical measurements.

Acid dissociation constants of epimeric threonines (Thr, allo-Thr) and isoleucines (Ile, allo-Ile) and the stability constants of their complexes with Co2+ and Cu2+ were determined by potentiometry. The natural epimers form more stable complexes than the allo forms. C.d. spectra of the complexes investigated were recorded, resolved into component bands and assigned.

The retention of 82BrO3− in KBrO3 activated with fast nuetrons is about 18% at ambient temperature. Annealing at 523 K gives an increase to 50%. Simultaneously produced 81mSe appears in about 90% as SeO42− at room temperature, which percentage increases to near 100% after annealing. The 76As recoil atoms appear 100% as AsO43−. A description is proposed, based on processes with different spectra of energies of activation. A model is given for these processes, based on the hypothesis that the recoil atom stabilizes in the host lattice in a form which is compatible with, and may be imposed by the crystal structure of the host lattice.

The 13C and 19F NMR of nine metal complexes contained perfluoroethylmonothio-β-diketonate ligands are recorded in chloroform-d. The complexes are of the type M[RC(S)CHC(O)C2F5]n where M is of nickel, palladium or cobalt; n is 2 or 3 and R is 2′-thienyl, phenyl or 2′-naphthyl. The 13C-NMR data support a fac-octahedral geometry for the cobalt complex (n=3). The 19F NMR show the chemical shift of the difluoromethylene group to be metal dependent. Correlations between the chemical shifts of the respective carbon resonances are also presented and NMR data for the three corresponding β-diketones, RC(OH) = CHC(O)C2F5, are described.
