N2 - The low-rotational levels of the b3Π- X1∑+(0,0) band of copper monofluoride, CuF, were recorded field free and in the presence of a static electric field. The field-free spectrum was analyzed to produce a refined set of fine and hyperfine parameters for the b Π3 (v=0) state. The permanent electric dipole moment, μ, for the b3Π(v=0) and X1∑+(v=0) states were determined to be 2.36(2) and 5.26(2) D, respectively, from the analysis of the observed Stark shifts. The experimental μ values are compared to theoretical predictions. The change in μ upon excitation and the hyperfine parameters are discussed in terms of the proposed electronic configuration for the b3Π and X1∑+ states. The optical Stark spectroscopy of the A2Π3/2- X2∑+ (0,0) subband of YO was also recorded and analyzed to precisely calibrate the electric field strength. The determined μ values are 3.714(5) and 4.542(40) D for the A2Π3/2 (v=0) and X2∑+ (v=0) states, respectively.
