摘要

The structural and dynamical properties of liquid ethanol (C2H5OH) at ambient conditions have been studied by ab initio molecular dynamics simulations using a large supercell containing 125 molecules (1125 atoms). The results obtained from a trajectory of 10 ps are found to be in good agreement with available experimental data. Without sacrificing accuracy, the computational cost of simulations is reduced by more than a factor of four by the linear scaling algorithm based on the augmented orbital minimization method.
