An attempt has been made towards explaining the observed frequencies in 63 Her. The evolution of rotating stars of 1.96, 1.98, 2.00, 2.05 and 2. 10 M-circle dot have been studied up to a point where stellar parameters match the observed luminosity and effective temperature of 63 Her. Radial and nonradial adiabatic oscillation frequencies were obtained in low harmonic degrees ( 1 = 0,1,2,3). One radial and three nonradial frequency values that match with the observed values were found for the model of mass 2.00 M-circle dot.
