For polyunsaturated alkenes, that have more than one double bond, the general formula becomes more complicated. Isotactic copolymers of 1-propene and 1-hexene that contain over 10% and up to about 25% of hexane units in the chain have been shown to crystallize in an unusual crystal modification that differs significantly from the well-known structures of isotactic polypropylene (α, β, and γ phases) or of isotactic poly(1-hexene) (Macromolecules 2005, 38, 1232). The rotational constants of the normal species are A=4269.564 MHz, B=1577.2661 MHz, and C=1469.6335 MHz. Structure of Ethene - the simplest alkene.
