Abstract: Electron paramagnetic resonance (EPR) measurement of single crystal CuGeO3 has been performed at 96GHz in 14K with 3.5T for a main axis g-factor. The admixture of d-orbital in the ground state wave function of Cu2+ ion in the spin-Peierls system CuGeO3 is derived. The g-factor is calculated with the aid of the approximate self-consistent field d orbit of Cu2+ ion. The experimental results can be well interpreted by the present theory.
