### Description |
|
|
Configurations of azobenzene featuring a cis to trans thermal inversion through three channels: inversion, rotation, and rotation assisted by inversion; and configurations of glycine as a simpler comparison molecule. All calculations were performed in FHI-aims software using the Perdew-Burke-Ernzerhof (PBE) exchange-correlation functional with the Tkatchenko-Scheffler (TS) method to account for van der Waals (vdW) interactions. The azobenzene sets contain calculations from several different MD simulations, including two long simulations initialized at 300 K; short simulations (300 steps) initialized at 300 K and shorter (.5fs) timestep; four simulations, two starting from each of cis and trans isomer, at 750 K (initialized at 3000 K); and simulations at 50 K (initialized at 300 K). The glycine isomerization set was built using one MD simulation starting from each of two different minima. Initializatin and simulation temperature were 500 K. |

# Usage |
|
|
- `ds.parquet` : Aggregated dataset information. |
|
|
- `co/` directory: Configuration rows each include a structure, calculated properties, and metadata. |
|
|
- `cs/` directory : Configuration sets are subsets of configurations grouped by some common characteristic. If `cs/` does not exist, no configurations sets have been defined for this dataset. |
|
|
- `cs_co_map/` directory : The mapping of configurations to configuration sets (if defined). |
