{To the Editors of the Journal of Physical Chemistry Letters}

\opening{Dear Editors,}
|

|
|
||
|
\justifying

Please find enclosed our manuscript entitled

\textit{``A Density-based Basis Set Correction for Wave function Theory''},
|
||
|
\end{quote}
|
||
|
which we would like you to consider as a Letter in the \textit{Journal of Physical Chemistry Letters}.
|
||
|
This contribution fits nicely in the section \textit{``Spectroscopy and Photochemistry; General theory''}.
|
||
|
|
||
|
One of the most fundamental drawbacks of conventional wave function methods is the slow convergence of energies and properties with respect to the one-electron basis set.
|
||
|
As proposed by Kutzelnigg more than thirty years ago, one can introduce explicitly the interelectronic distance $r_{12}$ to significantly speed up the convergence.
|
||
|
However, significant computational overheads are introduced by the large auxiliary basis used to resolve three- and four-electron integrals.
|
||
|
In this Letter, we describe a drastically different approach which combines density-functional theory (DFT) and wave function methods.
|
||
|
The present universal, density-based basis set incompleteness correction, which can be applied to any wave function method, relies on short-range correlation density functionals from range-separated DFT to estimate the basis set incompleteness error.
|
||
|
Our results clearly demonstrate that the present basis set correction recovers quintuple-$\zeta$ quality atomization and correlation energies with triple-$\zeta$ basis sets for a much cheaper computational cost compared to explicitly-correlated F12 methods.
|
||
|
|
||
|
Because of the large impact of our work, we expect it to be of interest to a wide audience within the chemistry community and beyond.
|
||
|
We suggest Paola Gori-Giorgi, Tim Gould, David Tew and Seiichiro Ten-no as potential referees.
|
||
|
This contribution has never been submitted in total nor in parts to any other journal, and has been seen and approved by all authors.
|
||
|
We look forward to hearing from you soon.
|
||
|

||
|
\closing{Sincerely, the authors.}
