P. Kirsch, J. Buchkremer, 0. Jaenlcke, R. Knoesel, R. Rumin, J. Shields, and E. Koerner von Gustorf, Meeting of the Photochemistry Group, German Chemical Society, Gottingen, 1973, Abstract 5. 

Partner members of each of these bodies may also have their own special interest groups e.g., Royal Society of Chemistry Photochemistry Group, German Group of Photochemistry (Fachgruppe Photochemie), Grupo Especializado de Fotoquimica (Real Sociedad Espanola de Qurmica), Photobiology Association of Japan etc. 

At that time the research in three fields (1), (2), and (4) was directly led by Prof. Kemula, while the photochemistry group in the laboratory was headed by Professor Zbigniew R. Grabowski—even though his early papers were in electrochemistry. His research in the laboratory was carried out independently, with the friendly...

The investigation of the photochemistry of steroidal cross-conjugated dienones was initiated by both Barton and Jeger and was pursued most extensively by the latter group. Despite the frequently complex product patterns which result from prolonged dienone irradiations, some prepara-tively convenient and useful methods for the synthesis of novel systems have been worked out in this field.

Of the four excitation types listed above, the n— n and n— n are far more important in organic photochemistry than the other two. Compounds containing C=0 groups can be excited in both ways, giving rise to at least two peaks in the UV. 

Photochemical reactions have the principal advantage of clean chemistry , as they use light of defined energy [72, 74], Synthesis of vitamin D and photocleavage of protection groups, for example, are accepted organic synthesis routes. Nevertheless, no widespread use of photochemistry has been made so far as this technique...
