Opis

The seventh of a series of prestigeous symposia on the photophysics and photochemistry of coordination compounds in 1987 called scientists from all over the world to the Castle of Elmau in the Bavarian Alps. Well-known researchers met to discuss recent advances in research. This proceedings volume of the 7th ISPPCC collects their contributions and provides an overview of theoretical and chemical aspects in six chapters: - Metal-centered excited states, - Photophysics and photochemistry of Cr(III) complexes, - Excited state properties of tris-2,2'-bipyridine-ruthenium(II) and related complexes, - Photoredox processes, - Organometallic photochemistry, - Methods, applications, and other aspects.
