✦ Synopsis
The directions of photoisomerization of polyenals and polyenones are believed to be controlled by the relative ordering of the n,n* and IT,IT* states.
The dependence of composition of photoisomers on solvent in direct irradiation of retinal (I) has been recognized for many years.3 That the ll-cis isomer is formed in alcoholic solvents
