{To the Editors of WIREs Comput. Mol. Sci.}

\opening{Dear Cl\'emence,}
|
||||||
|
|
||||||
|
\justifying
|
||||||
|
Please find enclosed our manuscript entitled \textit{``QUESTDB: a database of highly-accurate excitation energies for the electronic structure community''}, which we would like you to consider as an Advanced Review in \textit{WIREs Comput. Mol. Sci.}.
|
||||||
|
|
||||||
|
The present review summarises and extends our effort to build a comprehensive database of highly-accurate vertical excitation energies for small- and medium-sized molecules that we have named the QUEST database.
|
||||||
|
In order to gather the huge amount of data produced during the QUEST project, we have specifically created for the present article a brand new website [\url{https://lcpq.github.io/QUESTDB_ website}] where one can easily test and compare various theoretical methods.
|
||||||
|
We hope that the present review will provide a useful summary of our effort so far and foster new developments around excited-state methods.
|
||||||
|
|
||||||
|
We look forward to hearing from you.
|
||||||
|
|
||||||
|
\closing{Sincerely, the authors.}
