Abstract: We present an improved version of the method of photometric mode identification based upon the inclusion of non-adiabatic eigenfunctions determined in the stellar atmosphere, according to the formalism recently proposed by Dupret et al. (2002). We apply our method to ß Cephei, Slowly Pulsating B, δ Scuti and γ Doradus stars. Besides identifying the degree l of the pulsating stars, our method is also a tool for improving the knowledge of stellar interiors and atmospheres, by imposing constraints on the metallicity for ß Cephei and SPBs, the characteristics of the superficial convection zone for δ Scuti and γ Doradus stars and the limb-darkening law.
