The study of δ Scuti stars in a cluster allows to consider that all the objects have the same age, chemical composition and distance. In addition to this, the parameters like metallicity or distance are better estimated for stars belonging to a cluster than for typical field stars. We consider here a set of four Delta Scuti stars in the Pleiades cluster, observed in recent multi-site networks. We have calculated rotating stellar models with input physics appropriate to the star and cluster parameters. We have computed the adiabatic oscillation eigenfrequencies of the stellar models, up to second order in the rotational rate. A range of modes for each Delta Scuti star is presented.
