Z-/E- (cis-trans) Isomerisations

Z-/E- or cis-/trans- isomerizations are changes in the configuration of a molecule. This change can be induced thermally or with light.

 

The Video explains the theory behind and the actual experiment of the photoisomerization of azobenzene. Azobenzene can't be used in school experiments in germany. The explaining screentext is in German.
