A comparison between the oscillation frequencies of six multi-periodic Delta
Scuti stars of the Pleiades cluster and the eigenfrequencies of rotating
stellar models that match the corresponding stellar parameters has been carried
out. The assumption that all the stars considered have some common parameters,
such as metallicity, distance or age, is imposed as a constraint. As a result,
we have a best fit solution associated with a cluster metallicity of [Fe/H] ~
0.067, an age between 70x10^6 and 100x10^6 yr and a distance modulus of
mv-Mv=5.60-5.70 mag. All the stars were found to oscillate mainly in
non-radial, low degree, low order p modes. Estimates of mass and rotation rates
for each star are also obtained
