The VQM24 data set is a comprehensive data set containing QM properties of small organic and inorganic molecules. It encompasses 258,242 unique constitutional isomers and 577,705 conformers of varying stoichiometries, focusing on molecules composed of up to five heavy atoms from C, N, O, F, Si, P, S, Cl, Br. For each molecule, the data set provides optimized structures, thermal properties (vibrational modes, frequencies), electronic properties, wavefunctions, and, for a subset of 10,793 conformers, diffusion quantum monte carlo (DMC) energies. Calculations were performed at the ωB97X-D3/cc-pVDZ level of theory, with conformers initially generated using GFN2-xTB and subsequently relaxed using DFT. Calculations were performed with the following computational programs: Surge, RDKit, Crest, Psi4 and QMCPACK. The QCDGE database offers an extensive collection of ground and excitedstate properties for 443,106 organic molecules, each containing up to ten heavy atoms, including carbon, nitrogen, oxygen, and fluorine. These molecules are sourced from well-known databases such as QM9, PubChemQC, and GDB-11. The database provides 27 molecular properties, including ground-state energies, thermal properties, and transition electric dipole moments, among others. Ground-state geometry optimizations and frequency calculations for all compounds were carried out using the B3LYP/6-31G* level of theory with BJD3 dispersion correction, while excited-state single-point calculations were performed at the ωB97X-D/6-31G* level. All computational work was conducted using Gaussian 16.
