\noindent
For rovibronic states corresponding to the $B$ and $B'\ \Sigma_\mathrm{u}^+$ electronic states of the hydrogen molecule, the pre-Born--Oppenheimer (four-particle) non-relativistic energy is converged to a 1--3 parts-per-billion relative precision. The four-particle non-relativistic energy is appended with leading-order relativistic, leading- and estimated higher-order quantum-electrodynamics corrections \cite{SaFeMa23}. 
The resulting term values referenced to the rovibronic ground state are obtained in an excellent agreement with the experimental results \cite{BaSaVeUb10}. 
%
Further results are reported and discussed for other rovibronic states assignable to the $C\ ^1\Pi_\mathrm{u}$ and the $EF$, $GK,$ and $HH\ \Sigma_\mathrm{g}^+$ electronic states.
