Modeling the inter-molecular orientational correlation in orientational glassformers and the simulation analysis

Abstract

An effective bond model is proposed to describe the inter-molecule orientational correlation in orientational glassformers. The topological structures of the orientational correlation in the system are computer-smulated based upon the model. The results indicate that most of the bonding molecules appear in the form of molecular strings，and the phenomenon is explained using the probability theory. Furthermore，the simulated results are analyzed according to the string-model，and the rigourousness and feasibility of the model are discussed.
