The conjugation of the trans/cis product is likely diminished due to steric interactions between the cis-phenyl and the nearby vinyl hydrogen. This interaction likely causes the phenyl ring to twist out of the plane, and thus no longer to be fully conjugated with the adjacent double bond. The trans-trans isomer has no such steric interactions, and thus it is expected to be more fully conjugated. The two isomers are thus may have different light absorbing properties. Considering all this, which product stereoisomer do you expect to have the highest lambda max value in the UV-V is spectrum- the trans/trans or the cis/trans? Briefly explain your answer.
