IRAS measurements at 25, 60, and 100 μm have been used to analyze the infrared properties of Seyfert galaxies from the Markarian and NGC catalogs. One hundred sixteen of 186 Seyfert galaxies were detected. About 50% of all Seyfert galaxies in the sample have 60 μm luminosities in excess of ~ 10^(10) L_☉ , and the mean 60 μm luminosity increases with the optical B absolute magnitude. The luminosity functions of the Seyfert 1 and Seyfert 2 galaxies appear quite similar. It is possible, however, to statistically separate the two types of galaxies in color-color plots. The 100 to 60 μm energy distributions flatten systematically with increasing 60 μm luminosity. The infrared measurements provide a measure of the bolometric luminosity of the Seyfert galaxies but do not discriminate between the physical processes involved.
