MD Vibrational Spectra Simulation Skill

When to use this

Use this skill when the user has an MD trajectory and wants:

  • Power spectrum — velocity autocorrelation(仅需速度)
  • IR spectrum — dipole moment autocorrelation(需偶极矩,见 MLatom 文档

Inputs

  • h5md file — coords + velocities(IR 时需含 dipole,如 AIQM1/MNDO 轨迹)
  • xyz + vxyz — coordinates and velocities(IR 时另需 --dp 偶极档)
  • SMILES or xyz — 可 --run-md 先跑 GFN2-xTB MD

Outputs

  • /tmp/chemclaw/power_spectrum.png — power spectrum(--spectrum ps)
  • /tmp/chemclaw/ir_spectrum.png — IR spectrum(--spectrum ir,需轨迹含 dipole)

Theory

  • Power spectrum: 速度自相关的傅立叶变换
  • IR spectrum: 偶极矩自相关的傅立叶变换(需 dipole moments)
