Abstract

Accurate absolute level energies of the $B^{1} Σ_{u}^{+}$ , $v = 0 - 8, N$ and $E F^{1} Σ_{g}^{+}$ , $v = 0 - 21, N$ rovibrational quantum states of molecular deuterium are derived by combining results from a Doppler-free two-photon laser excitation study on several lines in the $E F^{1} Σ_{g}^{+} - X^{1} Σ_{g}^{+}$ (0,0) band, with results from a Fourier-transform spectroscopic emission study on a low-pressure hydrogen discharge. Level energy uncertainties as low as 0.0005 cm $^{- 1}$ are obtained for some low-lying $E^{1} Σ_{g}^{+}$ inner-well rovibrational levels, while uncertainties for higher-lying rovibrational levels and those of the $F^{1} Σ_{g}^{+}$ outer-well states are nominally 0.005 cm $^{- 1}$ . Level energies of $B^{1} Σ_{u}^{+}$ rovibrational levels, for $v \leq 8$ and $N \leq 10$ are determined at an accuracy of 0.001 cm $^{- 1}$ . Computed wavelengths of D $_{2}$ Lyman transitions in the $B^{1} Σ_{u}^{+} - X^{1} Σ_{g}^{+}$ ( $v, 0$ ) bands are also tabulated for future applications.
