The PCS141 Database

Download all PCS2 XYZ geometries.

Download all SE XYZ geometries.

Download all HPCS2 XYZ geometries.


The PCS141 Database compiles a comprehensive collection of geometries at both the PCS2 level of theory and Semi-Experimentals (SE). For each structure, the XYZ files are readily available for download, accompanied by vibrational corrections when applicable. Additionally, references to scientific publications pertaining to the data are provided.
