A cluster expansion is introduced for the determination of the optical absorption properties of cluster states in substitutionally disordered molecular crystals. This method is based on the Green’s function expansion in terms of the localized cluster states in the energy region of the guest subband. The general features of the method are illustrated by calculations for a simple two-dimensional ...

based on the fact the manipulation of fine nanoclusters calls for more precise modeling, the aim of this paper is to conduct an atomistic investigation for interaction analysis of particle-substrate system for pushing and positioning purposes. in the present research, 2d molecular dynamics simulations have been used to investigate such behaviors. performing the planar simulations can provide a ...

Identifying the conformations that a molecular cluster or polymer assumes in nature is an important problem with many practical applications in biology and medicine It is believed that the naturally occurring molecular conformations minimize or nearly minimize the potential energy of the molecular cluster or polymer The problem of nding the molecular con guration s with the lowest potential ene...

We present millimeter CO line emission observations of 12 galaxies within the Abell 262 cluster, together with L FIR data, in the context of a possible molecular gas deficiency within the region of the cluster center. Several indications of the presence of such a deficiency are highlighted and connected to a model of cirrus-like cloud stripping. The model predicts a drop in the average 100µm fl...

Molecular configurations which count as snapshots of a quasi-bound cluster are identified through a retrospective dynamical definition. The trajectory of a molecular cluster is followed, and a clear evaporation event is considered to have occurred when a molecule moves a very long distance away from the others. The cluster is judged to have broken before this condition is satisfied, however, at...
