In order to make clear the relationship between the pore structure and the diffusivity, we have carried out permeation simulations of pure gases through simple model membranes by using the external-field non-equilibrium molecular dynamics method. As

We investigate the static second hyperpolarizabilities ( γ ) of tetrathiafulvalene (TTF) and tetrathiapentalene (TTP) using the ab initio molecular orbital (MO) method. The cationic radical states of these systems (TTF + and TTP + ) are expected to

The second hyperpolarizabilities (γ) for three spin states (doublet, quartet and sextet) of π-conjugated molecules with a charged defect are investigated as a model of novel spin- and charge- modulated nonlinear optical systems. It turns out from t

The Lowdin spin projection technique has been applied to the calculation of the polarizability ( α ) and second hyperpolarizability ( γ ) of polyacetylene (PA) chains bearing neutral soliton or charged polaron defects. For both types of systems, α

In a previous paper we found that the cofacial intermolecular π-π orbital interaction in stacking dimers significantly changes the longitudinal second hyperpolarizability (γ) of the isolated monomer. On the basis of this result, we investigate the

The directional energy transport, i.e. exciton migration, in nanostar dendritic systems composed of two-state monomer units is studied using a quantum master equation approach. We examine the effects of the variation in the excitation energy of the m
