   Sammanfattning : Reactions of trans-dicyanodichloroaurate(III) trans-dibromodicyanoaurate(III), trans-diamminedichlorogold(III), cis-diammine(aqua)chloroplatinum(II), cis-ammineaqua-(cyclohexylamine)chloroplatinum(II), chloro(terpyridine)platinum(II) and chloro-(diethylenetriaminepalldium(II) with dimethyl sulfide, thionucleosides, thionucleotides and thione- and guanine-containing 17-mer oligonucleotides have been investigated by use of conventional and high-pressure stopped-flow spectrophotometry and HPLC technique as a function of ionic strength, pH, temperature and pressure in aqueous solutions. The mechanism and rate of oxidation of dimethyl sulfide by gold(III) complexes depends on the concentration of free halide. LÄS MER

4. 3. Synthesis and Structural Characterization of Copper(I) Complexes with Hard Donor Ligands

   Författare :Björn Gustafsson; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Acetonitrile; ­ -Sparteine; Chloride; co-ordination chemistry; Phenoxide; Alkene; Bromide; crystal structure; Copper I ; Amine;

   Sammanfattning : Syntheses and crystal structures of nine new copper(I) complexes and one novel mixed-valence copper(I/II) complex are reported: two homoleptic phenoxides and eight complexes with N-donor ligands. The copper(I) and the copper(I/II) phenoxide complexes have been prepared by reactions between mesitylcopper(I) and 2-allyl-6-methylphenol in toluene. LÄS MER

5. 4. Phthalate adsorption on gamma-alumina: a spectroscopic study

   Författare :Ottó Klug; Luleå tekniska universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chemistry of Interfaces; Gränsytors kemi;

   Sammanfattning : Adsorption of phthalic acid/phthalate has been investigated on anodically oxidized aluminium foils - used in wet electrolytic capacitors -, by different spectroscopic methods like UV, infrared, Raman and surface- enhanced Raman spectroscopy. In addition to the capacitor foils the adsorption was studied utilizing a high surface area, synthetic Y-aluminium oxide powder as a model material. LÄS MER

7. 5. Spectroscopic studies of solvation and adsorption properties of PVP

   Författare :Ildikó Száraz; Luleå tekniska universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chemistry of Interfaces; Gränsytors kemi;

   Sammanfattning : The adsorption mechanism of 1-vinyl-2-pyrrolidone (VP), poly(1-vinyl-2- pyrrolidone) (PVP) and azelaic acid on synthetic gamma-aluminium oxide surfaces was investigated using FT-IR, FT-Raman, UV, 1H and 13C NMR spectroscopy. (Liquid-solid state) As a first step the solvation of VP and PVP in solvents of varying polarity, specifically water, ethylene glycol (EG), chloroform and carbon tetrachloride, was studied. LÄS MER
