Amazing stuff! Molecular switches appears to be one hot topic in chemistry!
" ... molecules often possess unique properties that have no parallel in conventional materials and promise new hybrid devices with novel functions that cannot be achieved with equivalent solid-state devices. The most appealing example is the molecular switch. ..."
"A new technique for manipulating molecular rotations using the electric fields of light waves could provide insights into electrons’ movements during a chemical reaction ... Chemists understand in general that reactions occur when electrons lower their total potential energy by inducing atoms to reconfigure. Tracking electrons’ picometre-scale movements over the femtoseconds during which a specific reaction occurs, and understanding what influences the probability of the reaction occurring, however, remains a formidable challenge. ..."
