We study the influence of the angle between the two dipole transition momentson the group velocity for two kinds of three-level V-type systems withspontaneously generated coherence and incoherent pumping. The group velocity ofthe probe field for both kinds of the V-type systems alternates between thesubluminal or superluminal regimen. We can choose a real three-level V-typesystem from atoms or molecules to exhibit subluminal or superluminal lightpropagation by a proper geometry of the probe, coupling and incoherent pumpingfields, which depends on the angle between the two dipole transition moments.

The choice of a V-type system with the probe field in the subluminal or superluminal regimen
