Several lines in the A2Σ-(v = 0)-X2Πi(v = 0) visible band system of gas phase copper monoxide have been measured at sub-Doppler resolution using the technique of intermodulated fluorescence. The copper nuclear magnetic hyperfine splitting is clearly resolved. The observations were fitted to an effective Hamiltonian model and values of the magnetic hyperfine parameters of bF = -0.0302 cm-1 for the A state and d = 0.0024 cm-1 for the X state were determined. An interpretation of these values in terms of the proposed electronic configurations of these states is presented.
