| Abstract: | 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 A

of an analytical Hartree-Fock-Dispersion function. For the equilibrium parameters of the X state we get R
