Abstract: By using the techniques of stimulated emission pumping combined with fluorescence dip spectroscopy it has been possible to characterize the getastable $NO(L^{\prime}^{2}\Phi)$ state. The spectroscopic parameters are: \[ \begin{array}{ll} T_{e}=53740.81\pm0.20 cm^{-1} & r_{e} = 1.4204\pm 0.0037 \textrm{\AA}\\ \omega_{e} = 999.36\pm 0.18 cm^{-1} & \omega_{e} x_{e} = 9.92\pm 0.03 cm^{-1}\\ B_{e} = 1.1189 \pm 0.0029 cm^{-1} & \alpha_{e} = 0.019\pm 0.0027 cm^{-1}\\ A = -42.480\pm 0.032-0.310\pm 0.035(v+1/2) cm^{-1} & \end{array} \] The state is produced by initially populating $NO(B^{\prime}^{2}_{\Delta_{5/2}}, v = 3, J= 7.5)$ with 157.630 on radiation from an $F_{2}$ laser. While observing the $B^{\prime}-X$ fluocescence emission, a Raman-shifted dye laser is tuned through the appropriate spectral regions (950-1300 nm), and intensity decreases are observed at the positions of the J = 6.5, 7.5, and 8.5 rotational levels of the $^{2}\Phi$ state (as well as other states). The first four vibrational levels have been detected in this manner, with the numbering being confirmed by the recent matrix isolation detection of v=0 by Chergui et $al.^{1}$ Perturbations in the v=1 level of the $B^{\prime}^{2}\Delta$ state, postulated by $Huber^{2}$ as being due to the $L^{\prime}^{2}\Phi$ state, are shown to involve the v=9 level.
