Abstract
The relationship between the IR luminosity of spiral galaxies in the 40-120 mm range and their radio luminosity at 0.408,1.49,2.38,5.0, and 10.7 GHz is investigated. At all frequencies there is a close correlation between the radio luminosity and the infrared luminosity of spiral galaxies. The slopes of the relationships between radio and IR luminosities are less than unity at all frequencies, but they differ little from it within the error limits. A close correlation also exists between the fluxes of radio and IR emission. The correlation coefficients are high for objects of all morphological subtypes, while the relationships between radio and IR luminosities are nearly linear. They are also nearly linear for spiral galaxies of different classes in the Byurakan classification. It is also shown that the correlation between radio and IR luminosities is weakened for high IR luminosities.
