Study of the Unstable Rotational Dynamics of a Tor-Fullerene Molecular System

This work is devoted to modeling the dynamics of large molecules. The key issue in real molecular systems correctly represent temperature system using available theoretical tools. In most works on dynamics, vibrations atoms inside a molecule are modeled with enviable persistence, which has nothing do physical temperature. These energy internal molecule. Therefore, it should not be present problems inert systems. this work, by means classical mechanics, shown that simplest containing only three bodies, due multiple acts pair interactions these reproduces even an extremely complex unstable motion system. However, at same time, necessary separate stochastic part movement from deterministic one. Calculations also show translational fluctuations molecules make greatest contribution rotational total fluctuation motions small. It follows results thermal state determined latter, turn, opens up possibilities for simplified description many composed carbon such as fullerenes and nanotori.
