Both perturbative {\GW} (or {\GOWO}) \cite{Hybertsen_1985a, Hybertsen_1986} and partially self-consistent {\evGW} \cite{Hybertsen_1986, Shishkin_2007, Blase_2011, Faber_2011} calculations are employed as starting point to compute the BSE neutral excitations. These will be labeled as BSE@{\GOWO} and BSE@{\evGW}, respectively. In the case of {\GOWO}, the quasiparticle energies have been obtained by linearizing the non-linear, frequency-dependent quasiparticle equation. @@ -402,6 +403,31 @@ This step is, by far, the computational bottleneck in our current implementation \label{sec:PES} %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% +%%% TABLE I %%% +\begin{table*} +\caption{ +Equilibrium distances of ground and excited states of diatomic molecules obtained at various levels of theory.} +\label{tab:Req} + + \begin{ruledtabular} + \begin{tabular}{llcccccccc} + & & \mc{2}{c}{FCI} & \mc{2}{c}{CC3} & \mc{2}{c}{BSE@{\GOWO}} & \mc{2}{c}{BSE@{\evGW}} \\ + \cline{3-4} \cline{5-6} \cline{7-8} \cline{9-10} + Molecule & State & cc-pVDZ & cc-pVTZ & cc-pVDZ & cc-pVTZ & cc-pVDZ & cc-pVTZ & cc-pVDZ & cc-pVTZ \\ + \hline + \ce{H2} & $S_0$ & 1.438 & 1.403 & & & 1.440 & & 1.432 & \\ + & $S_2$ & & & & & 1.451 & & 1.442 & \\ + & $S_5$ & & & & & 1.781 & & 1.778 & \\ + \ce{LiH} & & & & \\ + \ce{LiF} & & & & \\ + \ce{HCl} & & & & \\ + \ce{N2} & & & & \\ + \ce{CO} & & & & \\ + \ce{BF} & & & & \\ + \end{tabular} + \end{ruledtabular} +\end{table*} + %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% \subsection{Hydrogen molecule} \label{sec:H2}
