<description>The QUEST database provides theoretical best estimates (TBEs) for more than 600 highly-accurate excitation energies of various natures (valence, Rydberg, \(n \rightarrow \pi^\star\) , \(\pi \rightarrow \pi^\star\) , singlet, doublet, triplet, charge transfer, and double excitations) for molecules ranging from diatomics to bicyclic molecules (see below). 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.</description>
