Evolutionary model calculations of 44 Tau, a δ-Scuti star, have been carried out. The star in question is a slow rotator (vsini = 6.8 kms-1). However small it may be, the effect of rotation on the oscillation properties of the star was thought to be worth of studying. Models were evolved with uniform rotation. Radial and non-radial adiabatic oscillation frequencies were calculated. In determining oscillation frequencies rotation has been treated as a perturbation. First order effect has been considered. The possible rotational splittings, due to two rotation speeds, have been calculated.
