The QM-22 database is a compilation of molecular data sets specifically curated for DMC calculations of the zero-point state. Each data set within QM22 employs unique methodologies tailored to the specific molecules involved. Detailed computational methods for each data set can be found in their corresponding publications. The CheMFi data set is a multifidelity compilation of quantum chemical properties derived from a subset of the WS22 database, featuring 135,000 geometries sampled from nine distinct molecules. CheMFi encompasses five different levels of fidelity, each corresponding to a specific basis set size (STO-3G, 3-21G, 6-31G, def2-SVP, def2-TZVP). The data set was generated using TD-DFT calculations with the CAM-B3LYP functional, performed via the ORCA software package. It includes comprehensive data on properties such as vertical excitation energies, oscillator strengths, molecular dipole moments, and ground state energies. Moreover, computational times for each fidelity level are provided to facilitate benchmarking of multifidelity models.
