The absorption spectrum of NaAr has been investigated with high resolution using a supersonic beam of molecules and a tunable dye laser. About 3 300 absorption lines due to the transition 
and 
have been observed. In addition, we observed the spectral distribution of the fluorescence for a particular absorption line. From all experimental data the 
interaction potential has been deduced in a fully quantum–mechanical method of approach. The potential is given in terms of an analytical Hartree-Fock-Dispersion function. For the equilibrium parameters of the X state we get 
Å and
