The observed rovibronic photoionization propensities and the quantum defects of the Rydberg series indicate that the photoelectron is ejected as a superposition of even (s and d) partial-wave components in agreement with predictions from the orbital-ionization model [S.

The ionization energies of the v$_{\textrm{2}}$$^{\textrm{+=3}}$ thresholds of NH$_{\textrm{2}}$D and ND$_{\textrm{2}}$H were determined to be IE / hc = 84 792.9(6) cm$^{\textrm{- 1}}$ and IE / hc = 84 595.9(8) cm$^{\textrm{- 1}}$, respectively, and rotational constants for the \textlessa name="ILM0002"\textgreater�\textless/a\textgreater = 3 states of both isotopomers are derived.
