WebTraditionally, double bond stereochemistry was described as either cis (Latin, on this side) or trans (Latin, across), in reference to the relative position of substituents on either side of a double bond. A simple example of cis-trans isomerism is the 1,2-disubstituted ethenes, like the dichloroethene (C 2 H 2 Cl 2) isomers shown below. WebThe intense color of carotenoids is caused by the strong extinction in the region, 400–500 mμ, where the spectral curve shows a massive band. If the latter exhibits vibrational fine structure, in most instances three maxima …
