The pressure broadening in the far wings, where the sodium Na (3p←3s) resonance line is perturbed by ground lithium Li (2s) atoms, has been theoretically analyzed. The NaLi potential-energy curves and the transition dipole moments are constructed by using a reliable ab initio data points to carry out the reduced-absorption coefficients kr(ν,T). This quantum-mechanical investigation have demonstrated that the NaLi profile spectra show a satellite future in the red wing at wavelength λ=685 nm in the temperature range 4000 K-1.8×104 K. The computation could also exhibit a second satellite, in the blue wing, near the wavelength λ=574 nm beyond 6000 K and a third peak located at λ=490 nm which begins to appear at 1.8×104 K.

Keywords:  pressure broadening      absorption coefficient      satellite structure      radiative lifetime
