Abstract: High resolution vacuum ultraviolet absorption spectra of $D^{13}CN$ and $DC^{15}N$ are photographed, especially for comparison with the so called $\beta$-X system, observed previously only for $DCN.^{1}$ Isotopic shifts establish the absolute vibrational numbering for this system yielding its assignment to the $\widetilde{A}^{1}A^{\prime \prime}-\widetilde{X}^{1}\Sigma^{+}$ transition. The measured bands between 53200 and $65100 cm^{-1}$ are thereby accommodated by a single electronic transition as predicted by $theory.^{2}$ New vibrational constants of the $^{1}A^{\prime \prime}$ state are presented for DCN as well as for the two heavier isotopes.
