Infrared photometry and later infrared spectroscopy provided powerfuldiagnostics to distinguish between the main emission mechanisms in galaxies:AGN and Starburst. After the pioneering work on infrared photometry with IRASin the far-IR and the S.Pedro Martir and ESO ground-based work in the near-IR,ISO photometry extended up to 200um the coverage of the galaxies energydistributions. Then Spitzer collected accurate mid-infrared spectroscopy ondifferent samples of galaxies. We will review the work done on the 12um galaxysample since the times of IRAS photometry to the new Spitzer spectroscopy. Themain results on the multifrequency data of 12um selected Seyfert galaxies arepresented and discussed in the light of unification and evolution models. Thespectroscopic work of Spitzer will soon be complemented at longer wavelengthsby the Herschel spectrometers and in the future by SPICA at higher redshift.
