Photoisomerization of stilbene: a spin-flip density functional theory approach.
The photoisomerization process of 1,2-diphenylethylene (stilbene) is investigated using the spin-flip density functional theory (SFDFT), which has recently been shown to be a promising approach for locating conical intersection (CI) points (Minezawa, N.; Gordon, M. S. J. Phys. Chem. A2009, 113, 12749). The SFDFT method gives valuable insight into twisted stilbene to which the linear response ti...
متن کاملAnother important coordinate in the photoisomerization of cis-stilbene
Detailed simulations are reported for the coupled dynamics of electrons and nuclei in the isomerization reaction of cis-stilbene stimulated by laser excitation. The results demonstrate that, in addition to the traditional vinyl and vinyl– phenyl torsions, the HCCH torsional coordinate of the vinyl group also makes a significant contribution to the HOMO and LUMO couplings that yield nonradiative...
متن کاملPhotoisomerization and energy transfer in naphthalene-terminated stilbene dendrimers.
Naphthalene-terminated stilbene dendrimers, the largest stilbene dendrimers to date, underwent photoisomerization via highly efficient energy transfer from the dendron group to the core stilbene. It was also demonstrated that the energy transfer efficiency in these dendrimers may be controlled by light, utilizing trans-cis isomerization as the key photoreaction.
متن کاملNonlinear-optical Christiansen filter as an optical power limiter.
We have constructed an optical power limiter based on nonlinear induced scattering in a cell containing crushed glass and a mixture of acetone and carbon disulfide. For 30-ps-long laser pulses the transmitted energy saturates at a value of 6 microJ. We also present the results of a theoretical modeling study that shows how the operating characteristics of such a device can be optimized.
متن کاملAb initio treatment of time-resolved x-ray scattering: application to the photoisomerization of stilbene.
In this work we present a general theoretical outline for calculating time-dependent x-ray scattering signal changes from first principles. We derive a formalism for the description of atom-atom correlation functions as Fourier transforms of quantum-chemically calculated electron densities and show their proportionality to the molecular form factor. The formalism derived in this work is applied...
