Accurate absolute level energies of the $B\,^1\Sigma^{+}_{u}$, $v=0-8, N$ and$EF\,^{1}\Sigma^{+}_{g}$, $v=0-21, N$ rovibrational quantum states of moleculardeuterium are derived by combining results from a Doppler-free two-photon laserexcitation study on several lines in the$EF\,{}^{1}\Sigma_{g}^{+}-X\,{}^{1}\Sigma_{g}^{+}$ (0,0) band, with resultsfrom a Fourier-transform spectroscopic emission study on a low-pressurehydrogen discharge. Level energy uncertainties as low as 0.0005 cm$^{-1}$ areobtained for some low-lying $E\,^{1}\Sigma^{+}_{g}$ inner-well rovibrationallevels, while uncertainties for higher-lying rovibrational levels and those ofthe $F\,^{1}\Sigma^{+}_{g}$ outer-well states are nominally 0.005 cm$^{-1}$.Level energies of $B\,^1\Sigma^{+}_{u}$ rovibrational levels, for $v \leq 8$and $N \leq 10$ are determined at an accuracy of 0.001 cm$^{-1}$. Computedwavelengths of D$_2$ Lyman transitions in the$B\,^1\Sigma^{+}_{u}-X\,^{1}\Sigma^{+}_{g}$ ($v,0$) bands are also tabulatedfor future applications.
