Photoassociation of ultracold long-range polyatomic molecules

Structure and dynamics of acetonitrile: Molecular simulation and neutron scattering

“…For our calculations, the reference frame was centered about the molecular center of mass, with the z axis pointing toward the methyl group. Although some of the tensor elements for the higher moments of ACN are nonnegligible, the value for the octupole moment is considerably less than the calculated values for fluoroacetylene [105,106], which we use as a benchmark molecule due to its linear geometry and the alternating signs of its charges. The small magnitude of the octupole moment suggests that electrostatic forces are not the driving force for the pairing that we observe.…”

Quantum control of reactions and collisions at ultralow temperatures

“…162 For photoassociation, the feasibility of the formation of triatomic molecules or tetratomic molecules has been analyzed in theory. 163–165 Preparing and controlling ultracold polyatomic molecules and studying the ultracold reactions involving them would largely enrich the research field and improve our understanding of ultracold molecules and ultracold chemistry.…”

Quantum Molecular Devices

“…A stabilization step is now required, either employing spontaneous emission, removing the electronic excitation, and transferring the entropy ballistically away or selectively dissociating the entity to the desired products. 43,44 When the field of coherent control was conceived, the dream had been to control the synthesis of molecules, 45−51 where the agent of control was quantum interference. 52 The theoretical dream was realized in numerous experiments, of which the overwhelming majority concentrated on photodissociation.…”

“…Upon electronic excitation, the interaction between the reactants becomes attractive, causing molecular fission. A stabilization step is now required, either employing spontaneous emission, removing the electronic excitation, and transferring the entropy ballistically away or selectively dissociating the entity to the desired products. , …”
