Many new transitions from the $(3s\sigma )A2\Sigma +$ state to higher Rydberg and valence states in $\mathrm{<mrow\; data-mjx-texclass="ORD">14</mrow>}N16O$ have been observed by the technique of optical-optical double resonance multiphoton ionization (OODR-MPI). Upper states include members from the np, nd, nf Rydberg states (n= 3 to 6) and several vibrational levels of the $B2\Pi$ and $L2\Pi$ valence states. The spectral simplification aspect of the double resonance technique allows for the observation of these spectra without appreciable band overlap. Analysis of our data leads to the identification of several previously unobserved mixed Rydberg-valence vibrational levels. Discussions of the Rydberg-valence interactions in the $68600-71200cm-1$ energy region of $\mathrm{<mrow\; data-mjx-texclass="ORD">14</mrow>}N160$ are presented in light of these results.
