Quantum chemical calculations of PCBM (part 1) [Data set]. https://doi.org/10.5281/zenodo.2074623810.5281/zenodo.20746238https://doi.org/10.5281/zenodo.20746238https://ir.library.knu.ua/handle/15071834/24957Quantum chemical calculations of PCBM (part 1): geometry optimization in ground state of C60, methyl 4-phenylbutanoate and PCBM in vacuum. All quantum chemical calculations were performed using the Gaussian 16 software package. Initial molecular structures were built using the Avogadro molecular editor [2]. The published dataset includes model structures of C60, methyl 4-phenylbutanoate, and PCBM. The calculation results are provided as output (.log) and checkpoint (.chk) files. Calculation details: Ground-state geometry optimizations were carried out at the DFT/ωB97-XD/6-311G(d,p) level of theory.
