Abstract
We have determined the central radio continuum fluxes at 6.3 and 2.8 c m from a subset of barred spiral galaxies from the Shapley Ames Catalo g with the 100-m radiotelescope in Effelsberg. We calculated the spect ral indices for the galaxies detected and we can see a weak correlatio n between flat spectral index and dust temperature calculated from IRA S fluxes, that is, T(d) greater-than-or-equal-to 30-degrees-K for gala xies having alpha6.3/20 greater-than-or-equal-to -0.75. The radio cont inuum at both frequencies and the far-infrared fluxes are strongly cor related.
