butadiene

The example of butadiene is used to make a connection with the pioneering dressed theory of Maitra et al Formal Foundations of Dressed Time-Dependent Density-Functional Theory for Many-Electron Excitations To make the relation between dressed TDDFT and the present theory more clear we present the example of butadiene previously treated by Maitra et al thus facilitating comparison with

Controlling guest conformation for efficient purification

Before 1 3-butadiene can be used to make polymers it must be separated from similar hydrocarbons in an energy-intensive distillation process Liao et al show that a zinc metal—organic framework can accommodate the cis isomer of 1 3-butadiene It binds less tightly than butane and butene because its π-bond conjugation is broken They used this preferential desorption to separate 1 3
