A sub-Doppler optical Stark measurement of the P1(1.5) branch feature of the A 2Σ-(υ′ = 0)-X 2Π3/2(υ = 0) subband system of gas phase copper monoxide, CuO, has been performed. The observed Stark shifts have been analyzed and a permanent electric dipole moment of 4.45 ± 0.30 D (1σ error estimate) for the X 2Π3/2 state determined. The results are discussed in terms of the various bonding models proposed for CuO.
