Calculated radiative transition probabilities between all vibrational levels in the $X1\Sigma +$ state $(v=0-21)$ and in the $A1\Sigma +$ state $(v=0=29)$ of NaH are given. In addition, the calculated spontaneous emission lifetimes for vibrational-rotational levels $(J=0,1)$ and the calculated dipole moments for these same levels are given. The calculation use new hybrid potential energy curves (based on Rydberg-Klein-Rees (RKR) and ab initio potential curves) and new ab initio dipole moment functions. The RKR curve for the X state is $new1$. The RKR curve for the A $state2$ and the at initio curves for both $states3$ are in the literature. The dipole moment functions of internuclear distance are also $new1$. $\mathrm{<mrow\; data-mjx-texclass="ORD">1</mrow>}$ R. E. Olson, B, Liu, H. T. Zerke and W. C.
