In a recent paper, we constructed the spectral energy distributions (SEDs) for 1425 Fermi blazars. We classify them as low synchrotron peak sources (LSPs) if log
14.0, intermediate synchrotron peak sources (ISPs) if
, and high synchrotron peak sources (HSPs) if
. We obtain an empirical relation to estimate the synchrotron peak frequency,
from effective spectral indexes
. In the present work, we investigate the correlation between the peak frequency and the radio-to-X-ray spectral index, between peak luminosity (bolometric luminosity) and γ
-ray/optical luminosity, and between peak luminosity and bolometric luminosity. Some discussion is presented.
