A versatile thin layer spectroelectrochemical cell employing specular reflection of the incident light beam from the electrode surface is described. Its application to in-situ uv–vis and FTIR characterization of the products of electrochemical reactions and to thin layer voltammetry and coulometry as well as conventional cyclic voltammetry is demonstrated for the oxidation of tetraphenylporphinatozinc in dichloroethane/tetrabutylammonium perchlorate solution. The advantages and disadvantages of this type of cell as compared to more conventional sandwich type optically transparent thin layer electrodes are discussed.

The Fourier Transform

The use of amber is documented in the Iberian peninsula since the Palaeolithic. The procurement and trade of this fossil resin has often been considered in discussions of long-distance trade and the emergence of social complexity, but so far no comprehensive view of the Iberian evidence has been produced to allow a more overarching interpretive model. This paper presents the Fourier-transform infrared spectroscopy (FTIR) characterization of archaeological amber from three Iberian prehistoric sites: a necklace recovered from the megalithic site of Palacio III (Almadén de la Plata, Sevilla), a pommel from PP4 Montelirio (Valencina de la Concepción, Sevilla), and a necklace from the Muricecs de Cellers cave (Llimiana, Pallars Jussà, Lleida). Based on these new data and a review of the literature, we present an overview that outlines fluctuations in the use of amber since the Upper Palaeolithic and demonstrates long-distance amber exchange connecting Iberia with northern Europe and the Mediterranean region since the Chalcolithic period at least. We discuss changes in the origins and cultural use of amber and their implications for the consolidation of trade networks.
