β¦ Synopsis
The internal motion of benzene is studied in the gas phase at 30 and 300 K and in the liquid phase at 300 K by means of a molecular dynamics method based on a hybrid of quantum and molecular mechanical force fields. The fluctuations of bond lengths, bond angles and torsional angles are calculated and compared with available experimental data. A conformational analysis for the planar, boat, chair and twisted structures of benzene is carried out and liquid benzene is found to be effectively a planar hexagon at room temperature.

Molecular dynamics simulations of pure benzene and a poly(oxyethy1ene) chain in benzene are performed. The simulation of pure benzene is found to agree excellently with previous simulations despite using a different force field. A comparison is made between the results of simulations of the poly(oxy
Conventional molecular dynamics simulations of macromolecules require long computational times because the most interesting motions are very slow compared to the fast oscillations of bond lengths and bond angles that limit the integration time step. Simulation of dynamics in the space of internal co
