In general, the isomerization occurs somewhat slower and exhibits a more disperse temporal behavior than for azobenzene. |
As the chromophore is a polyene, there are several double bonds capable of isomerization. |
The majority of quantitative reports have involved azobenzene, styryl or thioindigo structures, which undergo a cis-trans isomerization when photolyzed. |
Thus, a volume-conserving model seems to be needed for the isomerization of stilbene dendrimers with these large molecular weights. |
Most of those who died were in trailers next to the isomerization unit, which boosts octane in gasoline, when it blew up. |
Process of conversion consisting of the reactions of cracking, cyclization, dehydrogenation and isomerization. |
