Atmospheric chemistry and transport from isotopic analysis

Global change depends critically on the concentrations of gases present in the atmosphere at trace levels. The balance between the production and the loss terms governs the concentration of these gases. The stable isotope abundance can be used to provide insight as to the sources and regional and...

Synthetic and theoretical studies of N-confused porphyrins: A search for new ligands and coordination chemistry

N-confused porphyrins are a class of porphyrin isomers which have been known for almost a decade, being first isolated as by-products of one-pot porphyrin syntheses. They are known for the remarkable ease with which they form organometallic complexes. We plan to investigate a number of synthetic ...
