(B) Multi-elemental analysis by X-ray fluorescence. (use in Art, Archeology and environmental science)(1 week). The advent of inexpensive high-resolution X-ray spectrometers based on thermoelectrically cooled Si-PIN diodes has opened the possibility of many innovative experiments in analytical chemistry with many applications in art and archeology, environmental monitoring, nuclear medicine, to...

Mcissbauer spectroscopy is a nuclear i-rav resonance technique that has been extensively tv!i 'iill' s,,'stems. applied to the study of the electronic properties of iron in biological '. The power of the technique lies in its sensitivity to the effects of the physical environment (nature ]18 lw and disposition of ligands, magnetic structure, etc.) on 57Fe nuclei. Moreover, it is sensitive ' onl...

— Biochemists routinely use UV/visible spectrophotometry as a means of identifying and measuring the quantity of many biological compounds. When a new type of compound is isolated however, the method is often unhelpful in determining its chemical nature, and other spectroscopic methods must be used. The iron-sulphur proteins have recently been recognised as major components of bioenergetic syst...

(Cyclopentadienone)iron carbonyl complexes have recently received particular attention for their use as catalysts in hydrogenation or transfer reactions including the N-alkylation of amines with alcohols. This is due to easy synthesis from simple and cheap materials, air water stabilities, crucial metal-ligand cooperation giving rise unique catalytic properties. Here, we report a Mossbauer spec...
