The experimental results with in the double well of NaH D1Σ＋ state, can not match previous work and hard to confirm. So we are unable to analyze the experimental data. In this work we have observed 164 rovibrational levels among 17 vibration levels of D1Σ＋ electronic state near the dissociation limit. We have also found the possible signal of D1Σ＋ state dissociation limit. The De value of the ground state of molecular NaH can be deduced from the observed dissociation energy of D1Σ＋ state. This value is 15790 cm-1 which agrees well with Nedelec et al. results (15785±20 cm-1).
