This set is also chemically diverse, with organic and inorganic systems, open- and closed-shell compounds, acyclic and cyclic systems, pure hydrocarbons and various heteroatomic structures, etc.",

<p>This set provides a series of highly accurate vertical excitation energies for 30 (mild or strong) charge-transfer transitions obtained in 17 compounds (aminobenzonitrile, aniline, azulene, benzonitrile, benzothiadiazole, dimethylaminobenzonitrile, dimethylaniline, dipeptide, $\beta$-dipeptide, hydrogen chloride, nitroaniline, nitrobenzene,
nitrodimethylaniline, nitropyridine N-oxide, N-phenylpyrrole, phthalazine, and quinoxaline] computed from CCSDT/cc-pVDZ excitation energies determined corrected by CC3/CCSDT-3 energies obtained with the cc-pVTZ basis with further basis set corrections (up to aug-cc-pVQZ) obtained at the CCSD and CC2 levels.</p>

<p>The QUEST#7 subset is composed by 91 vertical excitation energies of 10 bicyclic molecules (azulene, benzoxadiazole, benzothiadiazole, diketopyrrolopyrrole, furofuran, phthalazine, pyrrolopyrrole, quinoxaline, tetrathiafulvalene, and thienothiophene).
In total, we provide aug-cc-pVTZ reference vertical excitation energies for these 91 excited states of these relatively large systems using CC3 and CCSDT.</p>
