alkene photoisomerization

https://doi.org/10.1351/goldbook.AT07320
Photochemical process with geometrical isomerization of a carbon–carbon double bond.
Notes:
  1. Geometrical @[email protected] of a C–C double bond is called a cis/@[email protected] @[email protected] in 1,2-disubstituted @[email protected] E/Z @[email protected] is a more general designation applying also to higher substituted @[email protected]
  2. This process leads to a @[email protected] if both isomers absorb light under the reaction conditions.
