【Abstract】 Electron paramagnetic resonance (EPR) measurement of single crystal CuGeO\-3 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 Cu\+\{2+\} ion in the spin Peierls system CuGeO\-3 is derived. The \%g\% factor is calculated with the aid of the approximate self consistent field d orbit of Cu\+\{2+\} ion. The experimental results can be well interpreted by the present theory.
