    Abstract: The adsorption and electrochemical surface reactions of 1‐naphthol on platinum in 0.5 M sulfuric acid were investigated by optical and electrochemical methods. At low anodic potentials (up to 0.65 V vs. dhe) monolayer adsorption of the organic molecule was observed with a significant extent of charge transfer. At more anodic potentials electrochemical polymerization occurs with films reaching several hundred Angstroms in thickness. Film growth is halted if the potential is decreased below 0.65 V. A parabolic rate of growth is observed and is attributed to slow, rate determining migration of electrons from the film/solution interface to the metal via the π electron systems of the polymeric film. At higher anodic potentials (above ca. 1.00 V) the parabolic growth law is no longer followed due to the occurrence of side reactions. The polymeric film is microporous, allowing passage of water molecules and ions at a low rate (low diffusion coefficient in the film). As a result the rate of electrochemical reactions on the film‐covered surface is diffusion controlled and depends mainly on bulk concentration, resulting with an apparent selectivity with respect to oxidation or reduction of the solvent.

    Abstract: Electropolished Ni(110) electrodes have a highly epitaxed 4 to 6 Å thick NiO surface film which is cathodically reduced in pH 2.8 Na 2 SO 4 solution with a current efficiency of ∼ 60%. This oxide breaks down rapidly on open circuit in the same solution giving an arrest structure which, in conjunction with surface activity measurements, indicates localized removal of a very defective film. The open‐circuit breakdown characteristics of anodically formed passive oxide films indicate that these films contain a localized distribution of defects within the oxide. The number of defects and their stability is found to be highly dependent upon the condition of anodization. With increasing time of anodization at potentials in the passive region, the number of defect sites decreases and/or their stability increases, i.e. the film becomes more perfect The corresponding decrease in anodic current with increasing time of anodization indicates a correlation between this current and the electrochemical reactions at the defect sites. The anodic current is due mainly to nickel dissolution which occurs after breakdown and during inefficient repair of the defect oxide. Analysis of the passive oxide film indicates the presence of 9 to 12 Å of NiO. The time and potential of anodization has little effect on the average thickness or stoichiometry of the passive film, the condition of anodization only influencing the small (≦2%) coverage of defect sites on the surface. The passive film can be cathodically reduced but with only a very low current efficiency. The results obtained with the Ni(110) surface are in general agreement with those previously obtained for Ni(111) and Ni(100) electrodes.

    Abstract: Techniques of signal assignment of 13 C‐NMR spectra of organic compounds, and in particular those of natural origin, are reviewed. They include symmetry, chemical shift considerations, spin‐spin coupling (both one‐bond and long‐range), spin relaxation (T 1 , NOE), isotopic enrichment and complexing agents. Special emphasis is given to the effects of oxygenated substituents on aromatic rings.
