## Description

- description: |
    Ab-initio phonon calculation for Ba(HO)2 / P2_1/c (14)
    Phonon band structure, phonon DOS, thermal properties at constant volume, and phonon raw data are presented.
    The initial crystal structure used to perform phonon calculation is obtained from the Materials Project using
    pymatgen MPRester. The phonon band structure paths are determined using SeeK-path.
