\begin{letter}%
{To the Editors of the Journal of Chemical Physics,}

\opening{Dear Editors,}

\justifying
Please find attached a second revised version of the manuscript entitled 
\begin{quote}
	\textit{``Reference Energies for Cyclobutadiene: Automerization and Excited States''}.
\end{quote}
We have taken two of the three optional minor suggestions of the reviewer into account as we prefer to stick with the more systematic EOM-SF-CCSD notations (point 2.).
In addition, we have taken into account the non-scientific changes requested by the editorial team.
We look forward to hearing from you.

\closing{Sincerely, the authors.}

\end{letter}
