Because GeoCities is bombarding visitors of the site with advertising I had to move the site to another place. You will find it in future at Rolf Claesssen's Chemistry Index http://members.freepage.de/chemistry/ oder fuer die Deutschen unter Ihnen http://members.freepage.de/chemistry/home_de.htm I will only update this site in the future.
