We applied the stepwise OODR excitation in our experiments. The OODR spectra of the NaH C1□＋ electronic state have been taken by monitoring the fluorescence depletion of the A1□＋ state to the X1□＋ state. We have observed 223 rovibrational levels (including 19 vibrational levels) of the C1□＋ electronic state, they are in the range of 36690 ~ 41500 cm-1. The observed vibrational level spacings of ΔGv＋1/2 are in the range 189 ~ 89 cm-1and derived rotational constants Bv are 0.488 ~ 0.636 cm-1. However, we have to confirm the absolute vibrational quantum number by a further study and the Dunham coefficients can be derived to construct the complete potential energy curve of the NaH C1□＋ electronic state.
