CO-H2: Structures Data
收藏资源简介：
This dataset was employed in the study of the adsorption dynamics of H<sub>2</sub> molecules on amorphous and crystalline carbon monoxide ice [1]. It was generated by combining exploratory MD simulations on CO and CO/H<sub>2</sub> clusters using the GFN-FF method [2]. Equispaced points in the trajectories were refined using density functional theory, and specifically BHLYP-D4/def2-TZVP [3,4]. The data is stored in python compressed array format (.npz) with the atomization energies in kcal/mol and atomic forces in kcal/mol/Ang. The data set contains five numpy arrays import numpy as np<br> data = np.load('CO_H2_BHLYP.npz')<br> data['R'] # Cartesian coordinates of nuclei (Ang.)<br> data['E'] # Total energy (kcal/mol)<br> data['F'] # Atomic forces (kcal/mol/Ang.)<br> data['N'] # Number of atoms in each structure<br> data['Z'] # Nuclear charges The dataset contains a maximum of 80 atoms per structure.
