The parameters of emission in the far infrared spectral range such as the luminosity and color, dust temperature, current star formation rate and star formation efficiency are derived for a sample of isolated galaxies. These parameters are compared with similar ones obtained for normal galaxies from the Virgo cluster. From comparison of the current star formation rates derived both from the luminosity in the far infrared spectral range and the emission in the radiocontinuum, the lower limit of the fraction of the galaxy free-free emission at 1.4 GHz is shown to be about 13 %.
