alkene photoisomerization
Photochemical process with geometrical isomerization of a carbon–carbon double bond.
  1. Geometrical @I03295@ of a C–C double bond is called a cis/@C01092@ @I03295@ in 1,2-disubstituted @A00224@. E/Z @I03295@ is a more general designation applying also to higher substituted @A00224@.
  2. This process leads to a @P04654@ if both isomers absorb light under the reaction conditions.
